Upcoming prototype / September 19, 2026
Version 28.6
A simpler assembly.
The new Fusion snapshot, with fewer separate CAD bodies, a flat board layout and an open speaker aperture. Explore the model and take the complete handoff into the next prototype review.
Experimental prototype · Fit review open. This publishes the supplied design with traceable exports. Physical qualification remains pending. Golden remains 28.1 / R3.4.

Bare shell. Rim envelope: 84.2 × 154.2 × 28 mm. Projecting details extend beyond the bare shell.
13 native CAD bodies across 11 supplied STL files. The shell/frame integration and material choices remain part of the prototype review.
Focus the model and use arrow keys to rotate, plus or minus to zoom, and Home to reset. You can also use the view buttons below.
September 19 native Fusion snapshot. Display colours and exploded spacing are illustrative. Hidden hardware/wiring and non-solid PCB sheets are omitted from this viewer; the original Fusion preserves them. Fit review remains open.
Native Fusion geometry. Colours and exploded spacing are illustrative. Historical hidden wiring/hardware and non-solid PCB sheets are omitted from the viewer; original Fusion retains the source content.
28.6 identifies this September 19 snapshot. The original Fusion filename retains 28_1_R3_6. This is a separate supplied design from the earlier 28.4 / R3.6 and 28.5 / R3.7 handoffs. Its 80 mm shell is wider than the preceding 78 mm version.

Source files, matched derivatives and a clear record of what remains to test.
- Illustrated guide
- Ten pages cover source authority, dimensions, parts, materials, actual CAD views, fit findings and first-article assembly.
- Native-position exports
- 13 individual STEP files and 13 STL alternatives, plus the 13-body review assembly and full reference STEP. Millimetres; import at 100%.
- Original source preserved
- The supplied F3D and 11 original STL files remain unchanged in the complete ZIP. Each derivative maps to its original occurrence and body.
- Build and test records
- Parts/materials, reference-body inventory, hardware and wiring review, assembly notes, open fit register, blank physical qualification log and file checksums.

The front shell contains two overlapping bodies whose manufacturing intent must be settled. Rigid, flexible and clear material proposals are recorded; no final process recipe, G-code, hardness or finish specification is claimed.
What the fit review found
The simpler direction is accepted. These engineering details remain open.
- Battery, board and play interfaces
- Native solid checks retain battery/rear-shell, board/shell, play-cap and play-switch-seat overlaps. Review these locally before a connected physical closure.
- Frame, acoustic layer and rim
- The two front-shell bodies overlap. The acoustic film needs its trim and placement defined, and the rim needs a specified material and intended compression.
- Wiring and hardware
- 48 hidden solid references remain in the original file. Their current relevance and fit need reconciliation; this flat-board design cannot inherit the connected-fit results from 28.5.
- Editable source health
- Five timeline entries retain missing-reference warnings. Cached geometry opens, but those references need repair and a regeneration check before treating the source as a dependable editable master.
Export reconciliation is complete: five solids in the supplied mesh set were about 5 mm higher in Y than native Fusion. The new exports use native placement without changing shape. All 13 individual STEP files import as valid solids and all 13 STL files are watertight. Static checks do not establish motion, strength or physical qualification.
All Version 28.6 files
One dated set. Original filenames and download checksums remain available.

The next step is a measured first article
Settle the open geometry and material decisions, reconcile the real hardware and connections, then record the physical build. The case must seat by hand without loading the battery, bowing the board or pinching wires.
The log includes dimensional checks, control travel, USB access, 10 proposed service cycles and 1,000 proposed actuations per control, followed by electrical, acoustic, optical and RF checks. No physical test pass is claimed.
