Custom feet for a Monoprice Mini Delta 3D printer that enable a webcam to be mounted for use with Octoprint or other remote monitoring software. Requires two 8.5 mm diameter aluminum poles or dowels 34 cm long. Has the added benefit of including air circulation under the printer.
I use the line infill pattern in Cura. You can use .4mm for speed, but then you may need to drill out the pole holes.
Print one left foot, one right foot, and one additional foot of your choice (either works for the back foot - the choice does not matter since you will not be using the back pole hole). Note that depending on the wall thickness, you may end up with a narrow column by one of the screw holes. Feel free to break this off as it does nothing. Print the webcam mount. I included a "thin" and "fat" version which are 2mm and 13mm thick respectively, depending on how thick of a mount your camera needs.
(While these instructions assume you want the camera mounted in the front of the printer, you can of course mount it on a side so you have easier access to the printer's control panel.) Attach the left foot and right foot in their positions on the front of the printer, so that the holes are facing forward, and each is angled up and in slightly (see the 4th picture above). You will need to remove three perimeter screws for each foot (see the 5th picture above), hold the foot in place, then put the screws back in. Attach the remaining foot on the back.
Insert two 8.5mm diameter aluminum poles or dowels cut to 34cm in length into the holes in the front feet. I had some spares from a tent pole replacement set ordered off Amazon (https://www.amazon.com/gp/product/B06XGBXQV5/). The ends of the poles should meet or just cross. Attach the camera mount to the end of the poles (see the 2nd & 3rd pictures above), attach the camera, and you are ready to go! Note the pole holes should be snug, but if they are not, just put a piece of tape around your pole.
