MX Lego Stem

Somebody mentioned a desire to make MX key switches lego compatible, so this is my implementation of that.

Tested for fit and functionality. I will say, the standard 2x2 lego brick sits a bit tall on this adapter, so a flat brick may be desirable, but I will need to test that the adapter height will fit on that.

Edit: I lowered the heights to make it work with flat bricks, and to not stick out too much.
