This is a wall mount I designed for the Dell OptiPlex Micro that SHOULD also fit the newer Dell Pro Micro series PCs that includes a small cubby port on the bottom to tuck the power supply away in and keep things neat.

Admittedly this mount takes a LONG time to print due to the 7 bazillion diamond holes I added for ventilation and aesthetics. I usually print an entire tray full of these things when I need them.

I print mine face-down with a 5mm brim to keep the corners from peeling up. Generally-speaking I use ABS filament to keep the mounts heat resistant and strong, and I use 30-40% infill.

The computer pushes in from the back and there's a plastic latch on the back side to keep it all held in.

Hopefully someone will find these mounts handy.
