This is a remix of Baialyn's design found here: https://www.thingiverse.com/thing:3127854
Removed the screw holes to allow a large flat surface for attaching to the wall with 3M strips, for those of us who rent and can't put hole in our walls. I also added a hole for the cable to pass through.
As with the original model I recommend a high infill (40%) for strength, preferably 3-dimensional such as gyroid or cubic.
The author remixed this model.
