Updated version of the power strip desk mount (no screws)
This version has thicker and longer holder arms to keep the power strip more secure.
Print 2+ hangers, hook them around the back of your desk, then slide your power strip through the hanger arms. You will likely need a wall behind your desk to keep the hangers from sliding off.
The .f3d file provided below includes parameters that you can edit to customize the mount to fit your needs.
My version used a desk thickness of 30mm, and a power strip cross section of 58mm x 30mm (if that matches your setup, you can use the stl file provided), but if your setup is different, open the .f3d file in Fusion 360 and customize the parameters to fit your needs.
