This is a base plate for tools. Check out my Magnet Mounting plate Thingy (25mm conduit) to distinguish the magnet holes from the rampa nut holes.

There is 0,5mm space between the two part, except for the bottom of the rest pin.
You can use a tool (can't refer to "THE" tool at the moment) to let the magnets stick out a bit, so that the holes on the side allign 100%. The holes on the side allign with the rampa nuts in the mount plate.

The 5 rampa nut holes in the middle are for something like a dual E3D mount like https://www.thingiverse.com/thing:1222291

Upper holes for the ajustment bar are a lineair pattern of 25mm.
Lower holes (4) have the following distance 6,75mm from the middle and the 2 holes on each side are 16,75mm apart from eachother.

(see messy picture)

P.S. will make a tool to push in the magnets and let them stick out 0,4 / 0,3 / 0,2 / 0,1mm
