Summary

I replaced the control board on my Ender-3 with an MKS Gen 1.4, and I needed a way to mount it to a 2020 (or 2040) profile.

The hole on the side is a close fit for an M5 SHCS, but an M4 should work too (with a little more play).

The hole on the bottom is 2.75mm diameter, and an M3 SHCS can be screwed in without needing to tap the hole, and will be a rigid fit. This hole is centered 4mm away from the vertical face of the webs, which accommodates both the MKG Gen 1.4 and the Raspberry Pi 3 B+.

I have both boards supported on three corners with these little guys, and the board feels solid and secure.
