My original mounting bracket was for a mac mini with a hub on the bottom of it, so it was a bit bigger than just a mac mini.  My friend asked me to make one that fits a standard mac mini, so here it is.  I cut the size and removed some of the supports that weren't needed… they were overkill and the bracket holds it just fine with the two supports.

I made sure there was space below it for air flow, but your mileage may vary.

I also added a logo for him, so unfortunately you'll get a logo in your print, but I added the fusion file so you can remove that if you wish.

Printed in PLA, screw to the wall and jiggle your mac into place.  It will go with a bit of pushing and twisting, but won't break the part… it's just flexible enough to give.
