Practical Guide: 3D Modeling and Printing Sunna's Microphone (Zenless Zone Zero)

In the dynamic universe of Zenless Zone Zero, the rise of the Angels of Delusion faction and its charismatic idol Sunna has set a new standard of technical demand for the creative community. For those seeking to execute the Guia Prático: Modelagem Rápida focused on 3D printing for Idol Accessories (Sunna's Microphone, in the context of Zenless Zone Zero) Cosplay prop making transcends mere visual reproduction, requiring a complex integration of digital design, structural engineering, and deep materials science. The character design, standing at 154 cm tall, incorporates a profusion of feline-themed details (such as cat ears and hairpins), pastel color palettes, white stockings, and a pearlescent aura that reflects her shy yet artistically brilliant personality, immortalized in vibrant performances like "Thoughtbop". Thus, materializing the iconic Sunna's Microphone requires a technical refinement that begins long before the printer nozzle heats up.

The transition from the virtual model to the physical plane requires meticulous planning of reverse engineering and ergonomics. 3D models extracted from or inspired by the game universe and optimized by the design community provide a starting point for the structural dimensions, presenting global dimensions of the reference model of 63.33 mm wide x 280.50 mm long x 316.02 mm high as the base scale. For cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in the slicing software (slicer) to a scale of 90% to 95% is crucial to preserve visual coherence. However, this alteration requires extra care: if the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making it impossible to insert the standard 10 mm PVC pipe used as internal structural reinforcement — which represents challenge number 1 in project planning. Given this, the physical integrity and the durability of the prop are inseparably linked to the choice of polymer material (filament) for high-fidelity 3D printing. The project's success, therefore, depends on a careful Polymer Analysis and Selection for 3D printing in Brazil, ensuring that the chosen 3D printing method offers lightness, ease of sanding, and mechanical resistance to withstand the routine of stage performances.

Introduction to the Project: Sunna's Idol Microphone

In the universe of Zenless Zone Zero, executing a high-level project requires precision and advanced technical planning. When we analyze the construction of items from this universe, it is clear that in Zenless Zone Zero) Cosplay prop making transcends mere visual reproduction, requiring a complex integration of digital design, materials science, and structural engineering. This Guia Prático: Modelagem Rápida addresses the development of the iconic Sunna's Microphone (also known as "Thoughtbop"). The character design, standing at 154 cm tall, incorporates a profusion of feline-themed details (such as cat ears and hairpins), pastel color palettes, white stockings, and a pearlescent aura that reflects her shy yet artistically brilliant personality.

To achieve a professional result in executing the 3D printing for Idol Accessories (Sunna's Microphone project, reverse engineering and correct scaling are fundamental. The first step in making a convincing prop is establishing a proportional scale. The object's ergonomics must be in harmony with the user's anatomy, preventing the microphone from looking like a tiny toy or a clumsy baton. 3D models extracted from or inspired by the game universe and optimized by the design community provide a starting point for the structural dimensions. * Global Dimensions of the Reference Model: 63.33 mm wide x 280.50 mm long x 316.02 mm high. * Base Scale: The aforementioned dimensions were established to ensure geometric fidelity.

However, scale adjustments in the slicer require mathematical and mechanical caution. For cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in the slicing software (slicer) to a scale of 90% to 95% is crucial to preserve visual coherence. However, the modeler must anticipate the impact of this reduction on the internal components: if the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making it impossible to insert the standard PVC pipe that acts as a structural reinforcement core.

Finally, additive manufacturing requires a careful choice of inputs. In the context of the Polymer Analysis and Selection for 3D printing in Brazil, both mechanical resistance and the durability of the prop are inseparably linked to the choice of polymer material (filament) for the 3D printing. The correct application of 3D printing techniques will ensure that the final prop not only mirrors Sunna's delicate and pearlescent aesthetics, but also withstands the rigorous routine of photo shoots and stages of large-scale events.

Reverse Engineering and Dimensional Specifications

To begin the Sunna's Microphone project from Zenless Zone Zero, the first step in making a convincing prop is establishing a proportional scale. The object's ergonomics must be in harmony with the user's anatomy, preventing the microphone from looking like a tiny toy or a clumsy baton.

As part of the Guia Prático: Modelagem Rápida for the 3D printing for Idol Accessories (Sunna's Microphone, Zenless Zone Zero) project, cosplay prop making transcends mere visual reproduction, requiring a complex integration of digital design, materials science, and structural engineering.

Scale Adjustment and Structural Tolerances

For cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in the slicing software (slicer) to a scale of 90% to 95% is crucial to preserve visual coherence. However, it is essential to anticipate the impact of this reduction on the internal fits: if the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making it impossible to insert the standard PVC pipe that serves as Structural Core.

Tolerance Alert: Millimetrically measure the internal diameter of the reinforcement channel in the slicer after applying the desired scale, ensuring that the physical support dowel or tube still fits perfectly without gaps or jamming.

Material Selection and Durability

When planning manufacturing, understand that the aesthetics and durability of the prop are inseparably linked to the choice of polymer material (filament) for the 3D printing of the external and internal parts. In the national propmaking scene, the Polymer Analysis and Selection for 3D printing in Brazil indicates the use of PLA for parts rich in cosmetic details and PETG or ABS for high mechanical stress connections, ensuring that the 3D printing of Sunna's Microphone (Zenless Zone Zero) withstands frequent handling at large-scale events.

Parametric Modeling Procedures in Autodesk Fusion 360

1. Sketch Setup and Reference Parameters: To start the development of your Guia Prático: Modelagem Rápida of Sunna's Microphone (the iconic accessory of the "Thoughtbop" group from Zenless Zone Zero), set up the workspace in Autodesk Fusion 360. Remember that, in the context of Zenless Zone Zero) Cosplay prop making transcends mere visual reproduction, requiring a complex integration of digital design, materials science, and physical manufacturing. Create a new sketch on the XY plane and establish the global dimensions of the reference model, which correspond to 63.33 mm wide x 280.50 mm long x 316.02 mm high. Draw a vertical construction line from the origin to serve as the axis of symmetry.

2. Two-Dimensional Profile Execution and Parametric Revolution: Meticulously draw half of the profile of the handle and the microphone body using lines and splines. While polygonal modeling and digital sculpting software, such as Blender or ZBrush, are exceptional for organic geometries (such as fabrics, furs, or textured armor), the construction of parametric, mechanical, and strongly symmetrical objects requires the precision of CAD tools, with Autodesk Fusion 360 being the ideal tool. With the profile closed, activate the Revolve operation. This tool converts a flat two-dimensional profile into a perfect three-dimensional solid by rotating it around a central axis. Select the drawn profile and the vertical axis created in the previous step to generate the main cylindrical volume instantly.

3. Parametric Dimensioning and Fit Tolerances: Design the internal channel that will serve as a guide for the support Structural Core of the microphone. The original character design, standing at 154 cm tall, incorporates a profusion of feline-themed details (such as cat ears and hairpins), pastel color palettes, white stockings, and a pearlescent aura that reflects her shy yet artistically brilliant personality. For cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in the slicing software (slicer) to a scale of 90% to 95% is crucial to preserve visual coherence. However, if the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making it impossible to insert the standard PVC pipe. Adjust this parameter directly in the Fusion 360 history to ensure that the diameter remains exact for physical assembly after 3D printing.

4. Structural Splitting and Manufacturing Preparation: Separate the three-dimensional model into smaller parts and add cylindrical alignment pins to facilitate post-print alignment and gluing. Remember that preparing for 3D printing for Idol Accessories (Sunna's Microphone requires that the durability of the prop are inseparably linked to the choice of polymer material (filament) for the 3D printing. Consult the Polymer Analysis and Selection for 3D printing in Brazil guide to select the ideal filament (such as PLA or PETG) before exporting the final STL files.

• Checkpoint: Before exporting the files to the slicer, use the Section Analysis tool in the Inspect menu to visually verify that the 10.3 mm internal channel maintains a constant diameter and that the thickness of the outer walls has not fallen below 2.0 mm at any point on the Zenless Zone Zero) model, preventing breakage and structural failures during manufacturing.

Analysis and

Fundamentals of Post-Processing and Smoothing Chemistry

The textural imperfections resulting from layer stacking in additive manufacturing instantly break the visual suspension of disbelief of the cosplay. The post-processing process, often inspired by automotive bodywork repair techniques, aims to completely conceal the polymeric nature of the object, transforming the striated plastic into a solid and perfectly smooth surface, worthy of a star's professional audio equipment. In the context of the Guia Prático: Modelagem Rápida focused on 3D printing for Idol Accessories (Sunna's Microphone, in the Zenless Zone Zero universe) The making of cosplay props transcends mere visual reproduction, requiring a complex integration of digital design, materials science, and surface engineering.

The structural strength and durability of the prop are inextricably linked to the choice of polymeric material (filament) for the 3D printing step (or 3D printing). According to the parameters of Polymer Analysis and Selection for 3D printing in Brazil, the thermal stability and chemical reactivity of the filament define how putties and primers interact with the piece, preventing cracks in the glue joints.

Chemistry of Correction and Leveling Putties

Surface leveling is not a single process, but the methodical iteration of filling valleys and sanding down peaks, engaging a variety of chemical compounds. The selection of the correction putty dictates the long-term stability of the paint. Two-component polyester putties (body filler/automotive putty) and high-solid polyurethane (PU) primers are applied to fill the FDM ridges, ensuring perfect molecular anchoring over the sanded polymer.

For Sunna's Microphone (known for the "Thoughtbop" theme in Zenless Zone Zero), the final finish needs to be flawless. The character's design, standing at 154 cm tall, incorporates a profusion of feline-themed details (such as cat ears and hair clips), pastel color palettes, white socks, and a pearlescent aura that reflects her shy yet artistically brilliant personality. To achieve this characteristic idol pearlescent shine, any print micro-grooves must be chemically eliminated before sealing.

Dimensional Analysis and Finishing Tolerances

During the physical preparation of the printed parts, dimensional fidelity must be maintained. 3D models extracted from or inspired by the game universe and optimized by the design community provide a starting point for structural dimensions. * Global Dimensions of the Reference Model: 63.33 mm wide x 280.50 mm long x 316.02 mm high. * Base Scale: The aforementioned dimensions were scaled to ensure the correct proportion with the character's body.

For cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in the slicing software (slicer) to a scale of 90% to 95% is crucial to preserve visual coherence. However, this downscaling directly affects the fit tolerance of the internal parts and the post-processing process: if the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making the insertion of the standard PVC pipe unfeasible.

Therefore, planning must be executed in rigorous physical steps:

• 1: Initial dry sanding with 150 to 220 grit sandpaper to break physical layer lines and open porosity in the polymer, followed by the first application of acrylic or polyester rapid correction putty.
• 2: Progressive wet sanding (320, 400, and 600 grits) interspersed with coats of PU primer, ensuring that the fit tolerances of the internal channels are preserved before structural gluing and final painting.

Advanced Painting Techniques and the Metallic Shine Paradox

In the context of a Guia Prático: Modelagem Rápida and 3D printing for Idol Accessories (Sunna's Microphone, aimed at the Zenless Zone Zero universe) The making of cosplay props transcends mere visual reproduction, requiring a complex integration of digital design, materials science, and surface engineering. Aesthetic fidelity and the durability of the prop are inextricably linked to the choice of polymeric material (filament) for the 3D printing, which makes the Polymer Analysis and Selection for 3D printing in Brazil the fundamental starting point before any paint application.

The character's design, standing at 154 cm tall, incorporates a profusion of feline-themed details (such as cat ears and hair clips), pastel color palettes, white socks, and a pearlescent aura that reflects her shy yet artistically brilliant personality. To replicate the iconic Sunna's Microphone, the centerpiece of her performance in the "Thoughtbop" style in Zenless Zone Zero, the cosplayer must master physical-chemical post-processing and multi-layer painting.

1. Dimensional adaptation and preparation of the 3D printing substrate: before starting any sanding step, check the physical dimensions of the printed piece. 3D models extracted from or inspired by the game universe and optimized by the design community provide a starting point for structural dimensions. The Global Dimensions of the Reference Model are 63.33 mm wide x 280.50 mm long x 316.02 mm high at the Base Scale. For cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in the slicing software (slicer) to a scale of 90% to 95% is crucial to preserve visual coherence. However, pay attention to the physical tolerances of the project: if the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making the insertion of the standard PVC pipe unfeasible. With the pieces ready, perform an initial dry sanding with 150 grit sandpaper to remove the coarsest plastic burrs.

2. Chemical leveling and surface correction: the textural imperfections resulting from layer stacking in additive manufacturing instantly break the visual suspension of disbelief of the cosplay. The post-processing process, often inspired by automotive bodywork repair techniques, aims to completely conceal the polymeric nature of the object, transforming the striated plastic into a solid and perfectly smooth surface, worthy of the audio equipment of a star like Astra Yao or Sunna. Surface leveling is not a single process, but the methodical iteration of filling valleys and sanding down peaks, engaging a variety of chemical compounds. Use the Chemistry of Correction Putties, as the selection of the correction putty dictates the long-term stability of the paint. Apply polyester putty or acrylic rapid putty over the ridges and perform sequential wet sanding with 220, 320, and 400 grit wet-or-dry sandpaper.

3. Application of specular bases and metallic systems: the photorealistic replication of these effects in the physical world requires much more than water-based acrylic paints applied with a brush, demanding multi-layer paint solutions. To obtain the polished metal effect of the microphone, use the Specular Bases and Colorgin Metallik Systems method. The use of metallic spray paints constitutes the most accessible and productive method for cosplayers to achieve realistic effects. In the Brazilian context, the Colorgin Metallik line (available in 350ml and 190ml cans) presents an excellent cost-benefit ratio (ranging from R$ 23.00 to R$ 65.00) and a wide portfolio of reflective colors, such as Rose Gold, Gold, Silver, and Copper. First apply a high-gloss glossy black paint base to serve as a reflective background and then apply quick, thin coats of the metallic spray.

4. Vitrification and application of iridescent pearlescent varnish: the aesthetic finish of Sunna's equipment in the game's ambiance reflects the state of the art of cyber pop, featuring sharp glints, radiant pastel tones, and iridescent pearlescent inserts. To seal and provide the necessary visual depth, apply a coat of high-gloss clear automotive varnish mixed with iridescent pearlescent pigment (such as ultra-fine mica powder). This will accurately simulate the characteristic pearlescent aura of the microphone under event stage lighting.

Quality Checkpoint: Before applying the metallic paint from Step 3, make sure that the primer applied after Step 2 is 100% cured and sanded with 600 grit wet-or-dry sandpaper. Run your fingertips over the curves of the microphone: if there is any step or print line noticeable to the touch, repeat the sanding and primer application. The metallic paint will act as a mirror and highlight any micro-imperfection that was ignored.

Integration of Electronic Systems (LED Lighting)

In the ecosystem of Zenless Zone Zero) The making of cosplay props transcends mere visual reproduction, requiring a complex integration of digital design, materials science, and structural engineering. The Guia Prático: Modelagem Rápida and the 3D printing for Idol Accessories (Sunna's Microphone (frequently associated with the "Thoughtbop" device of Zenless Zone Zero) require meticulous hardware planning so that the internal lighting works perfectly without compromising the physical integrity of the prop.

The character's design, standing at 154 cm tall, incorporates a profusion of feline-themed details (such as cat ears and hair clips), pastel color palettes, white socks, and a pearlescent aura that reflects her shy yet artistically brilliant personality. For Sunna's Microphone to realistically replicate this aura, the lighting systems must be embedded directly into the core of the object.

As step 1 of the structural planning, it is essential to consider the original physical dimensions of the project:

• 3D models extracted from or inspired by the game universe and optimized by the design community provide a starting point for structural dimensions. * Global Dimensions of the Reference Model: 63.33 mm wide x 280.50 mm long x 316.02 mm high. * Base Scale: The aforementioned dimensions were designed to ensure optimal proportionality.

However, for cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in the slicing software (slicer) to a scale of 90% to 95% is crucial to preserve visual coherence. Here lies technical challenge 2: if the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making the insertion of the standard PVC pipe for routing the electrical wiring unfeasible. Therefore, when planning the internal wiring and cable routing for the LEDs, use appropriate filaments and tolerances during slicing and the execution of the 3D printing.

The Analysis and Selection of Polymers for 3D printing in Brazil indicates that the thermal stability and the durability of the prop are umbilicaly linked to the choice of the polymeric material (filament) for the 3D printing of the translucent shell that will house the light-emitting diodes.

Electrical Architecture and Radial Emission

Translating the "Cat's Gaze" ability—a mechanical-ethereal anomaly linked to the presence of the mascot Bubblegum—into a physical object in the real environment requires internal electronic lighting. The luminescent effect on the microphone's upper sphere or peripheral ornaments establishes the turning point between a basic handcrafted prop and a hyper-realistic artifact.

The instrumentation of circuits embedded in a constrained volume is based on the basic theory of direct current electronics:

• Light Emitting Matrix: One should opt for high-intensity modular beams, such as pre-wired 3V super-bright LEDs, or small segments of 5V or 12V LED strips. The cylindrical encapsulation requires light to be emitted in all radial directions.
• Thermal Current Regulation (Resistors): The discrepancy between the power source voltage and the voltage drop inherent to the diodes makes the use of resistors an irrefutable prerequisite to avoid overheating the plastic filament and premature burnout of the components.

Aesthetic Finishing and Diffusion

The aesthetic finish of Sunna's equipment in the game's ambiance reflects the state of the art of cyber-pop: accentuated glows, radiant pastel tones, and iridescent pearlescent inserts. Photorealistic replication of these effects in the physical world requires much more than water-based acrylic paints applied with a brush, demanding multi-layer painting solutions.

For the metallic and opaque parts of the microphone, the "Specular Bases and Colorgin Metallik Systems" technique is the most indicated. The use of metallic spray paints constitutes the most accessible and productive method for cosplayers to achieve realistic effects. In the Brazilian context, the Colorgin Metallik line (available in 350ml and 190ml bottles) presents an excellent cost-benefit ratio (ranging from R$ 23.00 to R$ 65.00) and a wide portfolio of reflective colors, such as Rose Gold, Gold, Silver, and Copper. This metallic layer must be isolated from the light diffusion areas (made of translucent plastic), ensuring that the light from the internal LEDs passes homogeneously, without revealing the individual solder points or the circuit wires.

Occupational Health and Personal Protective Equipment (PPE) Protocols

In the context of the Guia Prático: Modelagem Rápida and 3D printing for Idol Accessories (Sunna's Microphone, Zenless Zone Zero), safety in post-processing is a non-negotiable pillar. After all, in (Zenless Zone Zero) The creation of props for cosplay transcends mere visual reproduction, requiring a complex integration of digital design, materials science, and structural engineering. Furthermore, the resistance and the durability of the prop are umbilicaly linked to the choice of the polymeric material (filament) for 3d printing, a technical detail deepened in the Analysis and Selection of Polymers for 3D printing in Brazil. The work of cosmetic engineering to bring Sunna's Microphone to life (associated with the performance of "Thoughtbop" in the universe of Zenless Zone Zero) mobilizes industrial-grade inputs that pose high risks to respiratory, immunological, and skin health, which is frequently ignored in amateur cosplay making channels.

1. Dimensional verification and model scale: before starting any physical finishing or sanding work on the piece resulting from 3D printing, ensure that the model meets ergonomic and assembly specifications. The character design, who is 154 cm tall, incorporates a profusion of feline thematic details (such as cat ears and clips), pastel color palettes, white socks, and a pearlescent aura that reflects her shy, yet artistically brilliant personality. 3D models extracted or inspired by the game's universe and optimized by the design community provide a starting point for structural dimensions. The global dimensions of the reference model are 63.33 mm wide x 280.50 mm long x 316.02 mm high. For cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in slicing software at a scale of 90% to 95% is crucial to preserve visual coherence. However, if the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making the insertion of the standard PVC internal support tube unfeasible.

   • Checkpoint: Use a digital caliper to measure the internal channel of the printed piece before proceeding to chemical and abrasive stages, ensuring the mechanical integrity of the fit.

2. Respiratory protection against PM 2.5 particulates during sanding: when performing layer line smoothing with rotary tools, keep in mind that the abrasive activity by micro-grinder volatilizes non-organic polymers in the form of PM 2.5 clouds directly dangerous to the alveolar airways. None of these pathogenic particles can be stopped by using PFF2/N95 dust masks, nor domestic fabric surgical masks, as the solvents are in gas form, freely infiltrating permeable fabrics. The specialized prop-maker community stipulates the irreducible use of original 3M masks and replacement cartridges, equipped with mechanical filters for fine particles (P3/P100).

3. Safe chemical handling of correction fillers: during surface leveling to eliminate imperfections from 3D printing, wear thick nitrile gloves and safety goggles. Polyester fillers release toxic peroxide compounds during exothermy, generating harmful vapors that attack mucous membranes and exposed skin. Perform mixing and application in locations with active exhaust or outdoors, keeping containers hermetically sealed when not in use to avoid saturating the ambient air.

4. Isolation and exhaust during synthetic finish application: when applying primer, paints, and varnishes to achieve the microphone's pearlescent aesthetic effect, remember that sprayed synthetic paints and varnishes aerosolize hydrocarbons and volatile organic compounds (VOCs). Use a paint booth with exhaust or work strictly in open areas, keeping the respirator with 3M brand activated carbon chemical cartridges properly adjusted to the face to retain organic vapors that easily penetrate common fabric barriers.

Alternative Methodologies for Scaled Budgets

1. Scale the model proportionally to ergonomics: so that Sunna's Microphone does not look like a tiny toy or an awkward stick, establish a proportional scale in harmony with the user's anatomy. 3D models extracted or inspired by the game's universe and optimized by the design community provide a starting point for structural dimensions. The global dimensions of the reference model are 63.33 mm wide x 280.50 mm long x 316.02 mm high. The base scale of the aforementioned dimensions was calculated for the character's standard stature. For cosplayers whose heights approach the character's canonical height (1.54 m), resizing the model in slicing software at a scale of 90% to 95% is crucial to preserve visual coherence.
   Checkpoint: If the model is reduced to 90%, the 10.3 mm central channel will become 9.27 mm, making the insertion of the standard PVC tube unfeasible. Ensure you adjust the internal channel tolerances before starting the slicing or physical assembly.

2. Select polymers for digital manufacturing: in the ecosystem of Zenless Zone Zero) The creation of props for cosplay transcends mere visual reproduction, requiring a complex integration of digital design, materials science, and structural engineering. To ensure the project's success, the durability of the prop is umbilicaly linked to the choice of the polymeric material (filament) for the 3D printing. When performing the Analysis and Selection of Polymers for 3D printing in Brazil, understand that the industrial workflow (FDM parametric integrated with automotive chemistry) aspired to by competitors presents high returns in texture and ballistic resistance, but entails considerable associated financial commitments (such as parametric software tooling and base printers).

3. Replace complex details with HD EVA manufacturing: the replication of the physical model under mitigated budget bases must resort to high-density (HD) chemical foam Ethylene-Vinyl Acetate (EVA) (EVA "Foam"). External details that would require countless hours in Fusion 360 software processes, in addition to extensive extruder delays, can be efficiently constructed through thermal cutting on sheet plates and adhesion to the structural core via instant epoxy fillers and the ubiquitous super-strong contact glue. The thickness of the EVA provides the desired bodily illusion (dispensing with solid base filament and reconditioning of striated FDM surfaces).

4. Apply the "Thoughtbop" thematic finish and sealing: the character design, who is 154 cm tall, incorporates a profusion of feline thematic details (such as cat ears and clips), pastel color palettes, white socks, and a pearlescent aura that reflects her shy, yet artistically brilliant personality. To reproduce this look economically, apply primer over the EVA parts and printed pieces to level the surfaces. This process of 3D printing for Idol Accessories (Sunna's Microphone, structured based on the Guia Prático: Modelagem Rápida, allows for blending the strategic use of 3d printing with manual finishing, reducing filament costs while preserving the aesthetic fidelity necessary to accurately represent the elements of the Zenless Zone Zero universe.
