The mount for the power that comes with the Dell Optiplex Micro is really pretty bad. The cover comes off; the mount doesn't stay connected to the computer mount very well . . . this solves that. 

this mount holds the power supply nicely under a desk or against a wall or whatever. Small amount of play but it grips nicely. Holes are included so the power supply can breathe a bit, but it works.

It has built-in supports - they snap off and make nice little “footballs” - although they're a bit sharp. LOL

It will print as it is, no supports needed.
