Remixed lukeskymaker Erro mount. Took off the side plate, put a hole in the middle to try and dissipate some heat. If you have these you know they get hot. Also added spacers in the rear to bring it out from the wall a bit for heat distribution.

Erro-mount-2.0.stl - has a pattern in the rear and would need supports. * I have not tried to print this one.

Erro-mount-3.0.stl - is just an open hole supports are suggested on the large opening. I opted not to do supports and you can see some issues in the pics but it didn't fail and its an easy fix.

I printed at .28 layer height (low quality) to save some time.
V3 print took little over 13hs at 50mm/s
