This is a support for a Chacon videophone screen. I've included a STEP file so you can modify for your own purposes.

In order to assemble the support you'll need:

-1 M5x65 (any) screw for the joint between the plates.

-1 M3x20 (any) screw for the joint between the lever and the screen plate.

-4 M3x12 (pan) screws for the connection between the support and the screen

-Nuts and washers as needed.

I only used support material on the wall plate so I could print the gear teeth for the ratchet mechanism. The remaining parts can be printed without supports
