Summary

I designed this part to hold the "LED&KEY" board. It keeps the circuits from shorting on my metal desk. Youtube user "Clough42" incorporated this part into his electronic leadscrew project. It uses a TM1638 I2C port expander.

I could not find prior art, so I drew one up in FreeCAD. I had to play with the hole spacing. The first time around they were a little off. I adjusted them slightly in the files here, but I did not reprint. It was perfectly usable as is.
