This isn't so much a remix as it is an inspired recreation. I added a 20° angle to it to allow the camera to use the vertical axis of the frame much more efficiently. This version is also much closer to the actual dimensions of the webcam so no shims are needed to keep it from wobbling around.
THIS IS NOT ALL YOU WILL NEED TO MOUNT YOUR CAMERA! You will need to use this https://www.thingiverse.com/thing:3372248 to mount it to a Creality Printer (Ender or CR10 series). I'm not sure if there are versions that support other printers.
You will also need to disassemble your C920 in order to remove the adjustable stand. I recommend this guide to do that. https://www.ifixit.com/Guide/Logitech+C920+Webcam+Disassembly/115077 Having an iFixit kit will definitely help, but it not necessary to do this. A simple eyeglasses repair kit will do the trick nicely.
