This is a wall mount specifically designed for the Logitech C270 webcam (with the base removed), a replacement faceplate, and a focus ring to adjust the focus on the fly. The faceplate and focus ring are a remix for my specific use case. I was unable to get the original focus ring to fit, so I upsized it a little and made the notches that nest into the stock focus ring a bit bigger. I saw no need to sandwich the focus ring between two faceplates, so I removed the outer faceplate and adjusted the inside faceplate to remove the holes necessary for mounting an outside faceplate - the faceplate can be mounted using the three screws that hold the stock faceplate. I printed the mount, faceplate, and focus ring at 0.2mm layer height in orange Hatchbox PLA and Galaxy Black Prusament PLA. The focus ring pressure fits on quite tight and will not fall off even though there is no external plate.

I have included the Sketchup files and .stl for all pieces.

EVERYTHING IS DESIGNED AT x10 SCALE so you will need to scale down to 10% in PrusaSlicer for printing.
