Another niche item, but possibly useful to a small set of people. I found a bunch of Logitech C910 designs here, but none that were quite what I had in mind, so I drew up this one.
Mounts to the bed support of the Monoprice Maker Ultimate (which is just a rebadged Wanhao Duplicator 6) so the camera is fixed to the bed, making the time lapse videos better.
Two designs - the initial had a clip to hold it in place, but I wasn't as happy with that design. It was what I did first and it works, so including it. The second design has provision for M5 set screws. No threads are included as I have a tap and die set which gives better results.
The camera mount itself has one side opened for an M4 bolt to pass through, and the other size smaller so it can be threaded for whatever M4 bolt you have on hand. Might work without a tap and die.
Original SketchUp design included.

Related: If you use OctoPrint, the autofocus on the C910 can be really annoying as the moving print head confuses it. To disable the autofocus and set it to what for me is the middle of the print bed:
- sudo apt install uvcdynctrl
- add the following lines to your /etc/rc.local before the exit 0 at the bottom:
uvcdynctrl -s "Focus, Auto" 0
uvcdynctrl -s 'Focus (absolute)' 122
Yes, I know /etc/rc.local is old school and sloppy, but it works.
Printed with supports, left some of them in place as I thought it looked cool.
