Unfortunately the great CH 341 Programer Enclosure from alanpwood did not exactly match the size of my CH341 programmer. So I decided to make my own version from scratch in Sketchup based on his design.

It has wider and stronger latches, larger cut outs for USB and the lever and it gently forces the programmer into a stable position in the enclosure.

I also made a small box for the CH 341 and its accessories, which you can find here:
