This is a remix of 0athbound's mount, it had an artifact that had a little gap that caused 100% infill so i fixed that and then added a cover for the exposed aluminum.

I may update the STL to add the nubs on the cover but we'll see how this 1st one prints out

The orientation i have set up here probably needs a tree support as the screw holes are on the face of the build plate but orientation probably doesn't matter much.

i think 10% infill is fine but i used 20% infill for mine.
