Update (7/22/2018): This part printed in PLA lasted about 11 months, 5 of which had heavy usage, before it drooped enough to hit the front of the printer when the y-axis moved to far forward. I do not recommend PLA for this print because of the low temperature resistance. Also, the camera vibrates a bit even when this part is brand new.
Update (8/20/2017): After a couple of weeks of use, I'm thinking that I can't recommend this design. It works for my needs (monitoring the print), but it didn't take long to loosen enough that there is a lot of jerk in the mount during prints which means that the feed is blurs every time the y axis changes direction. It still does the job for me, but there are probably better camera mounts out there.
A bed-mounted webcam mount for the Logitech C920 camera on the Wanhao Duplicator i3 Plus. Allows for objects to be stationary in frame when doing timelapses.
This mount requires loosening of the bed by a few millimeters in order to get mounted, but it just slides right on and stays in place really well. Requires a 1/4" screw on the bottom, but that screw also holds the two separate pieces together. Assembly is really easy once you slide the pieces onto the undercarriage of the print bed.
