Stacked on #66 (itself on #65): merge those first, then this one retargets to master. Not printed yet: changes for the next print.

From the first assembly (2026-11-14):

  • USB opening: Pro Micro moved back 1.8 mm, socket face 0.5 mm inside the outer face; opening 9 × 4 (socket only) instead of 12 × 8 (overmould). RXB6 moved with it (rx_y 31.3), over the same Pro Micro pins.
  • Screen less sunk: glass 1.2 mm below the face instead of 2.8 (oled_recess); pin joint groove keeps 0.7 mm of skin (assert).
  • Bottom window edge: horizontal in the world, so it opens outwards (40°) like the 45° sides and top, instead of looking inverted; prints as a flat bridge with the shell upside down.
  • Rail holes: noted to drill to 0.8 mm (1.2 mm holes print closed up).
  • Wiring guide: C2 10 µF may be tantalum 16 V (polarity) or an electrolytic laid flat.
  • receiver.3mf: first-print Orca settings committed, then meshes updated in place.

Checked: shell and plate render without errors or failed asserts; no intersection between the shell, the RXB6 (antenna included) and the Pro Micro (socket included).

Not changed: RXB6 still floats a little on its supports (glue, as planned).

hardware/receiver/ holds the tinyDecoders receiver docs, apart from the
tinySensor emitter boards: connections (colour, ends, length), pull-ups
and RXB6 decoupling, pin positions in the enclosure, the 1.9 mm headroom
under the RXB6 shield, assembly order.

From the first assembly:
- Pro Micro moved back 1.8 mm: its socket face sits 0.5 mm inside the
  outer face, and the opening shrinks from 12 x 8 (overmould) to 9 x 4
  (socket only). The RXB6 moves with it, over the same pins.
- Screen 1.2 mm below the face instead of 2.8 (oled_recess); the pin
  joint groove keeps 0.7 mm of skin (assert).
- Bottom window edge horizontal in the world: it opens outwards at 40°
  like the 45° sides and top, and prints as a flat bridge.
- Rail holes: note to drill them to 0.8 mm (they print closed up).
- Wiring guide: 10 µF may be tantalum (polarity) or a flat electrolytic.

The four screw pads printed as small islands near the edges (many short
moves). Each pad now hulls out to its corner and a 4 mm band along the
walls, as high as the pads, joins them into one frame: +1.3 cm³ (~1.6 g
PETG). Only contacts with the shell bosses and the Pro Micro pins.

…p to the face

The bosses were round columns hulled to their corner, leaving air between
them and the walls, and the front ones left an air pocket under the
screen. Each boss is now a square block from its wall corner to 3 mm
past the screw axis; the front bosses rise up to the face, minus a
keep-out behind the OLED and its wires (oled_back deep, from 2 mm below
the board edge). Plate pads are square too. The rear gussets stay.
