Eight keyed support posts now connect the two faceplates to the removable mounting tray. Each post has a lower assembly screw and an upper faceplate screw. The lower screws are installed from behind the tray before the tray enters the housing. One-millimetre hex keys locate the posts in shallow tray pockets; their torsional capacity is not qualified.

The upper supports are at X ±145 and Y 65/220 mm; lower supports are at X ±145 and Y −80/−235 mm. Bodies are nominally Ø12, extending from tray Z19 to the faceplate undersides at Z134 or Z133. The M4 screw/thread shapes are simplified development envelopes. Materials, machining details, tolerances, preload, thread capacity, support stiffness and vibration performance remain open.

All modeled new-part interference checks pass. The divider can rotate 20° and withdraw after the faceplates are removed. Its rotation was checked with conservative inflated envelopes covering every interval, followed by its continuous straight withdrawal envelope. With the divider and tray screws removed, the tray, posts and lower screws can withdraw together through the fixed enclosure. A nominal Ø10 driver barrel also clears the supports at each tray screw station. These checks omit actual electronics, wiring, hands and a qualified assembly/service procedure.

The STEP reimport contains 62 valid separate solids and passes the volume comparison. The inspection image hides the removed cover assembly and faceplates; its 43 visible CAD meshes were checked after reopening the Blender file. The image was visually reviewed.

This is a candidate geometry study, not a manufacturing release or a replacement for the completed Core R2 package. It has not yet been incorporated into the formal repository test suite. The earlier 38-part tray revision passed its separate 322-test full suite; that result does not cover this 62-part candidate. Divider attachment, rear-carrier retention, actual electrical packaging and physical qualification remain unfinished.
