Version 31

The same dimensions and fit geometry

The 73.5 × 143.25 × 19.4 mm body, control positions, openings, mounting interfaces and 22 printed pieces are preserved. Solid comparisons found zero added or removed volume in every printed part.

Ten understandable assembly modules

Enclosure, play, push to talk, volume, light indicator, USB, speaker, electronics, hardware and wiring allowances. PRINT and REF names separate fabrication parts from purchased items and fit references.

Repeated parts share one definition

Two PTT links, four shoulder sleeves and two speaker spacers now use three native parametric definitions. Four fully constrained sketches drive them, reducing the print geometry to 17 unique component definitions for 22 physical pieces.

A cleaner shell and timeline

75 redundant split faces were removed from the front shell: 951 faces become 876 without changing its solid shape. The rear shell remains unchanged. Three timeline groups organize the model; the saved file reopens with no timeline warnings.

Validated neutral exports

The complete STEP contains 468 valid solid bodies. The printed assembly contains 22. Individual files use millimetres and assembly positions. The rear-shell STEP serialization was repaired and checked without changing solid volume.

A prototype, with clear modelling limits

Complex shells and retainers remain exact solid base features. The body-dimension parameters are reference labels, not resizing controls. There are no motion joints, injection-moulding changes or new physical test results.

The professional reference uses a different, larger shell. Its dimensions were not copied or scaled into this release. The original v30 handoff remains available.

Warm ivory, the orange talk button, a stone-coloured silicone surround and a denser metallic grille are the intended appearance. Use the Inspiration photos tab to rotate horizontally through front left, front, right, back and left. Top and bottom studies appear below. The surround, grille border and woven mesh remain appearance proposals. This release focuses on the rigid 3D-printed prototype and preserves v30 dimensions.

Choose the right files

Use v31 Fusion for organised editing and the validated STEP for exchange. The individual bundle has 21 named STEP files and 21 named STLs for 22 pieces; the spacer file contains both spacers. Import at 100% in millimetres and orient individual parts in your slicer.

Keep the original print context

The complete handoff includes the unchanged v30 print source, with its five Bambu projects and original assembly information. These remain labelled v30. Slice and review before printing; no G-code or revised process recipe is supplied.

Record a physical first article

Check case closure, control return and travel, pivot fit, USB access, wiring clearances, adhesives, speaker stack, acoustics and optics with real parts. Static digital checks and watertight meshes do not prove physical performance.
