I made this mount for a coworker, he wanted to be able to mount his Samsung phone on his desk with a magsafe. He bought a MOUS-magsafe cover, and a magsafe charger.
I designed this so he could mount this to the shelf that holds his monitor.

The magsafe charger fits snug in the mount, the cable is routed through the bottom. It will fit a shelf up to 25mm. There is a printable screw, but i had to size it to 99% on X an Y-axis so it would fit easily. The mount is angeled at 75°, so you can easily glance at it while at your desk.
We tried it with an iPhone 14 pro and a Samsung S23 Ultra, both held fine.

It needs no post processing, but will require supports. I tried tree supports on the first print, and that came out sub-par. I then tried again with normal supports (you may have to enable to supports on the body too (for the angled parts) and not ‘buildplate only’)
I used 15% rectalinear infill and printed this in PLA.

On the coverphoto you will see the mount has a text on it, but that has been removed from the stl. feel free to add whatever you want :)
