A small case for home made electronic instruments. There are two versions of the base, the ESP8266 has mounting for an ESP-12F and a cutout for the USB socket. The plain version has slots for mounting PCBs or strip board.

There are also two fronts, one with a cutout for the 1.3" OLED screen and a Pot/Rotary encoder. The other one is a blank for making your own designs.

No supports required and I printed it in PLA.
