Articulating, Wall-Mounted, Magnetic Phone Mount Rotated Arm

UPDATE(8/6/18): Uploaded new PIN/SLOT version of 90 degree mount. Have had screws break on 3-4 different 90 degree mounts and got tired of it. Decided to design a new attachment system that works with as many original parts as possible. See my other design here (https://www.thingiverse.com/thing:3037099) for new Arms and Wall Mount using same PIN/SLOT system for extra strength. Make sure to use a PLA with some flex for the PIN (PLA+) so it won't break as you flex it to fit into the slot.
