The prompt
ed outline visible in the reference image. Create a recessed paint channel: Recess depth: 1.0 mm. Channel width: approximately 2–3 mm, adjustable. Follow the exact red outline pattern from the reference. Smooth channel edges. Make the channel suitable for filling with red acrylic paint. Keep the rest of the mask surface smooth. Only the designated outline areas should be painted red. 5. MASK CONSTRUCTION Main shell thickness: approximately 2 mm. Reinforce important structural areas. Provide comfortable internal clearance. Ensure adequate breathing space. Ensure visibility through the eye openings. Round internal edges to prevent skin irritation. Keep the mask lightweight. 6. FUTURE HORN COMPATIBILITY Do not model or include horns in this version. However, keep the upper forehead structure suitable for future horn installation. Do not create visible mounting holes or unnecessary sockets unless required for a future modular attachment design. 7. BAMBU LAB A1 MINI PRINTING Maximum component size: 180 × 180 × 180 mm. Divide the mask into sections where necessary. Use alignment pins and interlocking joints. Minimize visible assembly seams. Ensure strong connections between printed sections. Avoid unnecessarily complicated supports. Make every component manifold and watertight. 8. PARAMETRIC CAD Create a fully editable parametric CAD model. Use: Dimension-controlled sketches. Extrusions. Loft features. Fillets and chamfers. Separate editable features. Recessed paint-channel geometry. Keep the red outline channel independently editable. 9. FINAL DELIVERABLES Generate: Complete mask CAD model. Separate printable mask sections. Recessed red paint channel. Alignment pins and joining components. Dimensioned technical drawings. 3D assembly preview. Individual STL files. Editable source CAD file. FINAL INSTRUCTION Prioritize accurate reproduction of the uploaded reference image, facial fit, comfort and successful printing on the Bambu Lab A1 Mini. First generate a 3D preview and show the dimensions before finalizing the model. Do not add horns in this version. Do not invent missing design details. Ask for clarification when necessary.
