4Max Side cover for Mosfet Install

Created a side cover that adds room to install a mosfet for the heated bed.

You will need 4 3mm screws to mount the mosfet.

I have added the Fusion 360 model if you want to edit anything, it should be fairly parametric. I left a little extra space for clearance, you may be able to shrink it down some through trial and error. It works for me so I am happy.
