I wanted to to mount my Wyze cam on the gantry so that it would follow my prints better. I also like the view looking down as opposed to up from the low mount I had been using. There were a couple of mounts similar that I came across, but I couldn't find a logical way to print them without a silly amount of support, so I decided to make my own.

This mount slips right over the X-axis stepper cover on an Ender-3/Ender-3 Pro and does not require any tools or hardware to install.

The mount does require support to print, but if you look at the orientation in my photos, I believe this orientation minimized the amount of support required.

For cable management I used a couple "LSF's" or "sticky-backs" and zip ties to run the USB cable down the arm. To be honest, after I printed it, I thought I could have added cable clips, but that would require more supports, so this solution works. Feel free to change it up if you want. You could probably also just run zip-ties through the truss structure if you wanted.

I run my Wyze cam with their "beta" webcam firmware connected to OctoPrint, and it works great.

I have included a file with my wolf cutout and a plain one that you could add your own design to.
