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.
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.
Regenerate all previews for the current model, embed the nameplate and
section views, and correct the screen/FPC captions (ribbon exits the

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.
