An arm to mount a Logitech C270 webcam to the bed of a Robo 3D printer. Perfect for monitoring prints with OctoPrint! Video of the mount and camera in action: https://youtu.be/1TroQwgVaAQPrint out both the camera mount arm and the spacer block. Hook the arm over the Y axis carriage just to the left of the center bed support and line the hole up with the one in the right side of the Y carriage. Slide the spacer block into the pocket one back side of the carriage where the hole is. Use a 1-1/2" #6 machine screw and nut to secure the arm and spacer block through the hole in the carriage. Use a couple of zipties to secure the camera to the end of the arm. There are two mounting options allowing you to secure the camera to either the horizontal or vertical face of the arm.
