Carriage Mounted Camera Holder for Prusa i3 MK3S+

prusaprinters

Most models I found were designed to attach to the frame, which meant that during a print, the camera would not always be looking at the model. The camera arm attaches using a M3x25 countersunk screw that replaces the one in the bottom tight corner of the carriage. Arm is kept in place with a M3 lock nut.The camera enclosure is designed specifically to a USB camera like the one shown in the picture. The camera needs to have at least a 120 degree field of view due to the proximity to the printing surface. The camera can be screwed to the “middle” part using M2x8 self tapping screws. Same type of screws are used to attach the front and back to the middle part. The camera feed will probably need to be rotated 180 degrees in octoprint.The enclosure needs M3 brass inserts so that it can be attached to the U-Bracket using M3x8 screws.Parts are pre-oriented for printing. I used PETG for the arm but you might want to consider using ABS or ASA if you intend to print using materials that required high bed temperatures. Some of the heat from the bed might transfer through the screw onto the carriage and arm.
