I wasn't entirely happy with other models, so I created my own.

• minimal size to protect all header pins
• cutouts for USB port, the 2 buttons and Dupont connectors

You just need 2x countersunk M3 screws or friction fit the top (for this you might scale _top a bit, depending on the accuracy of your printer)

Printed mine in PLA with 0.2mm layer height, 0.4mm line width - no supports needed

If there is interest for a ESP32 _top version and this fits in the same _bottom let me know the length of the hearer row and I'll create it.
