This bracket will mount a Mac Mini to the back of a monitor with 100mmx100mm mounting holes.
Print four (4) of the clips to make a top and bottom for each side. Install all four clips to make your Mac Mini Bracket.
The Mac Mini should be a snug fit sliding in from the side.
You may need to get longer screws for the monitor. I used M4-.7 x 20mm Flat Head Philips Screws. Depending on your monitor you may need longer or shorter screws.
