ASI BAC8000 Controller Case Mount

Check the splits in the Prusaslicer .3mf files; it's designed to be printed in PETG then change materials to TPU for a builtin gasket to seal against the Q140 universal controller plate. There's a lip to seal against the frame for cable entry just beyond the plate.

This revision/remix fixes hole spacing slightly, has simpler joinery for splitting (the short distance triangle pattern resulted in gaps at triangle corners) and a bit more space for cable routing (I have 22x of 20ga silicone, 3x 10ga nomex phase wire, and 6x 8ga silicone for the battery).
