I designed a geared phone holder, simply because I find it gears cool ;) 

I printed it in PETG (because of low shrinkage issues), but in theory any rigid material would do.

The phone holder can be used in the horizontal position (on a table) or can be mounted on a vertical wall. Also the phone itself can be used in portrait and landscape orientation.

I'm not gonna ask for a coffee, but please make sure you give me a like if you find this model useful.
