Ever had a crappy time dialing in your fitment and too lazy to do the math on what spacers you should run? Well, that makes us both.

So I made a test spacer with a 5mm base plate 5mm shim and 10mm shim to go under the plate.
The base is made for M12 to M14 (If you dial your printer properly) studs and has three bolt patterns. 5 x 100, 5 x 114.3 and 5 x 120. Sorry 4 x 100 guys, I'll throw one up for you as well.
The center bore is 62mm

Pretty sure I don't have to tell you guys...but do not drive with these on.

For the base plate, it's better to do 5-6 walls, no top or bottom layer, and 5-6 infill lines.
