placeholders — a custom carrier PCB will re-fix them later.
The flex leaves the glass's back plane on the left and must fold ~180 deg
to dive into the cavity toward the breakout. A safe bend radius makes
that loop ~4 mm deep, too deep for the 1 mm foam gap, so it fouled the
rigid bracket. Open the bracket's left frame member and the foam's left
border over the FPC span, aligned with the body's existing slot, to give
the U-turn room. Re-adds the relief dropped in c4320e2, correctly scoped.
Was only rendering assembled + body, which let bracket.png drift stale.
Now covers all 11 views. Recovered the two bespoke cameras that were
never recorded: nameplate (straight-on body) and front34 (low back 3/4).
Reverts the notch added in 6af959f. The flex U-turns off the glass's
left edge and returns inboard through the ~1 mm foam gap above the
bracket, then drops into the cavity through the aperture — it never
crosses the bracket plane, so the relief in the body's pocket wall is
enough. A solid frame also clamps that edge more evenly. Comment added
so the notch doesn't get reintroduced.
Gap in the left frame member aligned with the body's FPC clearance so
the flex folds back through the bracket plane into the cavity instead
of being pinched. Refresh renders and the bracket alt-text.
Factor the two halves of the horizontal cut into shared modules so each
can be viewed alone (`plan_up` = deck/screen, `plan_down` = cavity),
while `plan` keeps the exploded combo. Cut height and gap are now the
`plan_z` / `plan_explode` params.
New `show="plan"` lifts the deck/screen half off the cavity half so the
board layout reads at a glance — standoffs, corner posts, ports, and the
internal FPC clearance. Tunable via `plan_z` and `explode`.
The ribbon accommodation must not be visible from outside. Drop the cut
below the bezel lip so the flex folds back into the cavity with no notch
breaking the external face.
Regenerate all previews for the current model, embed the nameplate and
section views, and correct the screen/FPC captions (ribbon exits the
left, breakout on the left, wiring to the ESP32).
The screen's flex leaves the LEFT short edge (user's left), so route it
there: an open ribbon bay in the left bezel, the DESPI-C579 breakout in
the cavity below it, and SPI wiring across to the ESP32. Add a modeled
foam gasket, a `show="section"` cutaway of the screen clamp, and
`active_off_x/y` for the panel's off-centre active area.
Typewriter-body OpenSCAD model for the GDEY0579T93 panel and
ESP32-S3-DevKitC-1: glueless screen retention (bezel lip + foam gasket
+ screwed bracket), baseplate-as-chassis board mounting, and a recessed
deck nameplate. Ships render previews, a dimensioned concept drawing,
and just recipes to open/render/export.
