ESP32 C3/C6/S3/H2 Super Mini Case

A basic case for the different ESP32 Super Mini boards. Lid clicks in place quite firmly. With optional pass-through for wires.

Variants

The different boards have different dimensions. This repo contains generated STL files for 23mm and 24mm boards. Measure your board and take the one that fits best. Or generate your own with the OpenSCAD tool.

Custom sizes

Created using OpenSCAD, using BOSL2 and hex-grid libraries. Variable size cases can be generated using SCAD source.

    // Regular case, default dimensions for C3 Super Minin board
    case(18, 23.2, 8.5);

    // Same case, but with pass through for wires
    cable_case(18, 23.2, 8.5);

    // A closed lid
    lid(18, 23.2);
