This is a modified end for a wall mounted phone holder to hold a Samsung Galaxy Note 9 in a Spigen Tough Armor case. I printed in PETG for extra strength but you do it how ever you want. It is a little big to help accommodate a thicker case so it isn't snug. I plan to line it with felt to take up that last little bit and make it softer inside. Here is the wall mount this goes to: https://www.thingiverse.com/thing:2448971 .stl is orientated in the manner I printed it for strength.
Edit: Just posted this: https://www.thingiverse.com/thing:3311587 to go along with this phone holder and to go with the original wall mount. It adds a 90 Degree turn to the end of the mount.
The number 2 is there for my iterative purposes. Ignore it.
