ESP32 dev board case, all parts — All parts, as they come off the printer2 parts

Technical details

Parts: body — open-top shell with edge-slot cradle for the hole-less dev board, micro-USB opening, side vents, cable grommet, four M3 heat-set bosses beyond the PCB ends. The cradle is an open ledge (no top lip): the DevKitC header bodies run to the board edge, so the board is retained by the lid, not by a slot. lid — flat plate with drop-in lip and four M3 clearance holes. Both parts are returned in print orientation (bed at z=0): body floor down, lid top face down.

ESP32 dev board case

A small enclosure for an ESP32 DevKitC with a USB opening, side vents and a cable grommet.

These boards have no mounting holes, so the case holds the board by its edges and the lid keeps it seated. Four screws close it.
