I like the design for the Logitech C270/C310 webcam holder for the Prusa i3 MK3/S from GiantBrain very much. Thanks for that!
Unfortunately the mounting hole for the x-axis is just suitable for one single position and allows no movement. But since the x-axis motor holder allows slightly movement for tightening the belt, it is pretty much possible that you will miss the mounting hole. Therefore I made the hole a bit wider for adjustments now or later.

Since the webcam case was a bit loose and did not hold a certain position, I added another version with a nut hole for a tighter fit. It is suitable for a m3n-nut and a M3*25 screw.

I re-aligned the nut hole since it was shifted. Thanks to @grgbss01 for mentioning.
