Left X-Axis Friction Fit Mount I put together to mount my Logitech C920 on the Ender 3 S1. You should be able to use any webcam that has a standard 1/4" tripod mounting screw insert. You will need to print out a 1/4" screw to mount your camera. This is the one that I used:

UPDATE 4/8/22
I am uploading an updated model with an improved fit and longer arm for mounting.
Clarification: This model should be printed with the arms straight up with support on build plate only since there has been questions on it.
The author marked this model as their own original creation.
