This is a webcam mount for a XYZPrinting Da Vinci Duo 2.0a (though it may well fit other Da Vinci printers). It's designed for a webcam that uses a standard 1/4" tripod mount, and has been designed specifically for the Logitech C615 webcam (which works with both AstroBox and Octopi). Other cameras that are narrow and use a tripod mount likely will work as well. It has sufficient clearance to not get in the way of the print head, yet gives a good view of the action.
This mounts to the frame of the Da Vinci, rather than on the print bed itself. Since the Da Vinci moves the hot end in both X and Y, there is no need to place this on the bed to get nice time-lapse movies. The Da Vinci seems a bit picky about print bed calibration so I decided to not risk having the extra weight hanging off the bed.
You will need to remove the left side cover to install. This is easy to do, just place a stiff blade (like a putty knife) under the lip on the top and lift a bit. There are around four snaps that will release (all along the top) and the side will come off. Then you can insert the mount into the holes on the inside and simply snap the side cover back on.
Supports are required, but the STL is already oriented to minimize the use of them. Do make sure to look at your supports generated in a g-code viewer, as some slicers will think the clips are too small to get supports (but actually they do much better with them). All the supports are easy to remove since they don't attach to a large surface.
