Objective: Redesign 3D chibi astronaut character with modular electronics integration and removable components. Primary Design Requirements 1. Removable Visor (Helmet Glass): Design front visor to be completely detachable from helmet Use snap-fit mechanism with cantilever hooks (minimum 5mm wide) or M3 threaded connection for secure attachment Create mating groove 2-3mm wide between visor rim and helmet for easy assembly Transparent visor can be printed with clear filament or leave opening for acrylic sheet insertion Visor wall thickness: 1.5-2mm for durability Add 0.5mm radius fillets at snap-fit base to reduce stress concentration Deflection angle: 30-45° for optimal insertion/retention balance 2. Back Panel Design: Entire back of body and head should be hollow with removable cover plate Internal cavity dimensions: minimum 50mm x 40mm x 25mm to accommodate ESP32 and OLED display Back cover with 4-6 snap-fit retention points or 4 corner mounting holes (M2/M3 screws) Cover rim thickness: 3mm with O-ring groove or lip seal for secure closure Cover can be flat or follow original model contours 3. ESP32 Module Compartment: Internal mounting rails or standoffs for ESP32 board (25.5mm x 18mm dimensions) Screw posts or snap clips positioned according to ESP32 standard mounting hole spacing Minimum 30mm width clearance for easy board insertion/removal Ventilation slots (2-3mm wide) on side walls for heat dissipation Clearance tolerance: 0.4mm around board perimeter 4. OLED Display Compartment (0.96 inch): Mounting frame for OLED screen (27mm x 27mm overall, 24mm x 12mm display area) Display can be positioned behind visor on front face or on character body If front-mounted: create rectangular viewing window 25mm x 13mm in visor or front panel Display retention frame with 4 x M2 mounting holes, 2mm thick rim around screen Maintain 0.3-0.5mm tolerance for display fit 5. Type-C Port Integration: Type-C port location: back panel (top/bottom edge), side, or base of model Port cutout dimensions: 9mm x 3.5mm with 0.5mm chamfer for easy cable insertion If ESP32 has onboard Type-C: align cutout directly with board connector, create channel if using breakout cable Clearance around port: add 2mm on each side for accessibility Optional reinforcement frame 2-3mm thick around port opening 6. Internal Cable Management: Cable routing channels 3-4mm wide from ESP32 to OLED display Integrated clips or tie-down posts for securing jumper wires Additional 5-8mm clearance space for wiring and auxiliary components Modular design: separate head and body sections if needed 7. 3D Printing Technical Specifications: Recommended layer height: 0.1-0.2mm (0.15mm for precision snap-fits) Wall thickness: minimum 2mm for structural integrity Infill: 20-30% for shells, 100% for snap-fit features and mounting posts Support structures: required for visor undercuts and snap-fit hooks Fit tolerance: 0.2-0.3mm for snap-fits, 0.4-0.5mm for screw threads Print orientation: snap-fit arms horizontal (XY plane), NOT vertical to prevent layer delamination 8. Additional Features: Mounting hole for keychain attachment or lanyard Base weighted or widened for stability when electronics are installed Preserve cute details: eyes, bubble tea cup, chest emblems Consider asymmetric snap-fit hooks: shallow angle (30°) for insertion side, steeper (45°) for retention 9. Material Recommendations: PETG or Nylon for snap-fit components (better flexibility than PLA) TPU for highly flexible cantilever arms if needed Standard PLA acceptable for rigid structural components Output Files Required Separate STL files for each component: front body, back cover, visor, ESP32 mounting bracket, OLED frame Assembly file to verify fit before printing Exploded view diagram showing assembly sequence
