Needed a wall mount for a WD external HDD, the larger sized ones that have a power supply. Whipped up this wall mount in Fusion and after 2 attempts getting my measurements dialed in everything fit perfectly.

I printed in PETG with 20% infill because the drive can warm up a bit under load and isn't featherweight.

Supports are recommended unless your printer bridges 20mm gaps acceptably for the plug access.
