A small case specially made for a 128x64 OLED screen and a D1 Mini. The OLED is fixed with a small bar on the back (no screws). The front and the back can be inserted without glue. USB port of D1 Mini is accessable from the back.

The D1 Mini is a type without holes and can be slided in without glue too. 2 resistors for the I2C bus are directly soldered to the OLED screen.

I used “Archemdian chords” as the bottom infill pattern for the front cover.
