Logitech C270/C310 Focus Ring

I wanted to add focus ring to my Logitech C310 webcam, but I didn't like beefy designs I found here, so I have started with original design and I slimmed it out to make it look better, and also to use less material for printing.


Additional hardware required:
2x M3x6 socket head screw


Post-printing:
You may want to cut thread in holes for M3 screws in "back" using M3 tap


Installation:
1. Take off front cover of camera (it is clipped on)
2. Unscrew inner cover, keep 3 screws for assembling Focus Ring
3. Remove glue from camera lens, so lens threas would be free ald will allow rotation.
4. Attach "back" to camera using 3 screws kept in step 2
5. Put "ring" on lens
6. Attach "front" using M3x6 screws
