Leveling Feet for Moai (20x20 aluminum extrusions)

Designed for my new Moai printer in mind. The desk my printer sits on isn't quite level anymore, so I made some little feet for it to sit on that I can adjust the height on to get it more level. More to lessen my anxiety of it rocking back and forth than improve printer performance (or so I believe).

Because it's designed for 2020 extrusions, I believe it should work for other printers/projects as well.

I can also upload the Fusion files, if so desired.
