Version 28.7

Shell details

The front shell and rear shell change locally. The previous play-cap/front-shell and both PCB-laminate/shell overlaps are absent above the 0.001 mm³ reporting threshold.

LED housing and light guide

The LED housing and one optical body have local material removed. The second optical body is unchanged. Optical performance and the LED housing’s connected fit still need testing.

Reference connections visible

The source now shows 15 hardware and 32 wire solids that were hidden in 28.6. The inside view includes them; the exploded view hides these groups for clarity.

A fresh rear-shell export

The supplied rear-shell STL is byte-for-byte unchanged from September 19 even though Fusion’s rear shell changed. This handoff includes a newly generated rear-shell STL and STEP.

Use the native-position set for this update. Original files are retained for traceability. The supplied rear-shell STL is superseded by 07_Rear_Shell.stl in the new parts package.

Illustrated guide

Eleven pages cover changes from 28.6, source authority, dimensions, parts, materials, actual CAD views, remaining fits 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 parts ZIP is for prototype review. 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.

Battery, board components and switch seat

The 40.761 mm³ battery/rear-shell and 10.800 mm³ play-base/switch overlaps remain. A new 0.114 mm³ rear-shell/resistor contact needs local review. Cleared laminate and play-cap overlaps do not establish complete board clearance or full button travel.

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

15 hardware and 32 wire solids are now visible, with one wire body still hidden. Their modeled contacts need classification and reconciliation; making them visible does not establish connected fit. This layout cannot inherit the 28.5 harness or screw schedule.

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 current native placement and geometry. The supplied rear-shell STL is stale; use the regenerated 07_Rear_Shell file. 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.
