Update:  Uploaded a v2 with more rounded shapes, and the magnets placed on the underside of the stand, and added a few mm of height.

I found the camera housing from https://www.thingiverse.com/thing:3419695 by RossIRL very useful on my Ender 3, but when I changed to a CR-10s Pro v2 I no longer had extrusions to attach it. So i quickly went into Fusion 360 and wipped up a magnetic base for the same camera housing.

The magnetic mount uses 3x8mm Neodymium disk magnets that I purcased of ali express, and makes the mount sit secure without beeing stuck so hard that you cant slide it around if need be.

On my printer the disc and camera house sits very well as a friction fit, but if your printer is not calibrated you might need to adjust the size or use a drop of glue.
