Mounting Plate for Rotary Phone

Mouting adapter for an old rotary phone to a modern phone wall mount plate.

Old rotary phones were meant to screw directly into a wall. Newer phones mount on a plate on the wall. This is an adapter to mount an old phone to a new phone wall mount.
By Old, i mean 60's era rotary phone, and new i mean 80's era wall phone. 'Modern' phones mount plug into the wall using an RJ11 plug and 2 posts above and below the RJ11 plug, the size of a normal wall outlet.

I used some M3 screws and threaded inserts to mount the phone to the 3d printed mount. The 3d printed mount will slide onto the 'modern' wall mount.
