This is a camera mount to attach a Logitech webcam (designed for a QuickCam Chat for Skype) to the bed of a Robo 3D R1.

The camera mount part may work for other models.

The printer side of the mount attaches to the front middle of the bed, between the glass and the middle support. The camera side of the mount screws onto the swivel that comes attached to the camera.

Instructions on how to take apart the camera are at:

Those instructions don't go into disassembling the swivel, but it's just a cotter pin and 3 PH00 screws.
