This case mount is a remix for a Rpi4b of the Rpi3b Prusa Mk3 Frame Mount Case by 3D_Dynamics. It works perfect in the Prusa MK3.

The half hexagon on the end of the arm hooks into the hexagonal cut out on the top of the z axis, and the bottom bolts into the pre-existing threaded holes in the Mk3 Frame. There is lots of clearance behind the case, and some clearance in front of the case even with the heads of the bolts sticking out. This should allow for access to the gpio pins if you choose to wire directly to the einsy board, but I have not tested this.

Required Hardware

-Two m3x10 bolts from spare parts bag to mount the case to the frame. This length will sit flush on the other side of the frame once tightened. -Four m3x18 bolts from spare parts bag to join the two case halves. This length worked well for me, you would be able to get away with other similar lengths if you don't want to use the spare parts bag from Prusa. -Four m3x6ish bolts sourced for mounting the board. Length isn't super important, as long as they are short enough
