I wanted more deskspace at work so I made a desk mount for my phone. This is the most recent version. I had made previous versions with no cable tie spacing or only 2 rows of mounting points. The best improvement over my older revisions was making the under-desk portion thicker. There is a space for a cable tie to loop through.

My print was made with rigidity in mind so the infill doesn't need to be as excessive:

Material — PLA+ (Tough PLA) (FDM)
Finish — Standard (100% infill)
Color — Black
