Arduino MEGA + RAMPS holder (T-slot frame) + K8200 rail adapt

I re-designed the holder for using RAMPS in K8200 instead of the original board. However I keep in mind that it could be useful for T-slot printer bars, I used it in Wilson as well. I embedded the nuts for easy assembly and for their fixation.
Note that the cylinders are used as isolation washers to avoid the M3 screws damaging the board.

Bill of Materials:

M3 Screw 20 mm x 3 (or you can use one of 25mm to hold the board together with RAMPS shield, as you see in the picture)
M3 Nut x 3
