Oneplus 12R mount for RAM, AMPS

This design allows mounting a OnePlus 12R phone with OnePlus Sandstone bumper case using RAM or AMPS compatible accessories. The design allows one-handed insertion, removal of the phone from the mount. In addition to the printed parts, the following hardware is required:

4 x M3 x 8 bolts
4 x M4 x 12 bolts
4 x M4 standard nuts
1 x AMPS adapter plate for 1 inch ball mount or similar (38mm x 30mm M4 hole pattern)

Assembly is pretty straight forward. I intend to glue the camera shim to the mount after testing it for a few days.

This design is an update of my Pixel 2XL and Oneplus 7T mount found here: https://www.thingiverse.com/thing:5477772
