Logitech C310 Focus Ring and Coverplate

thingiverse

[EDIT 2019-09-29] Added several photos to illustrate the disassembly and assembly process. I'm using a Logitech C310 webcam with Octoprint on a Prusa i3 MK3 (and another on a MK3S). The focus setting on the C310 was not quite right. This can be adjusted by removing the cover plate, adjusting the lens, and then replacing the cover plate. I wanted to adjust it again easily if needed, and I found a design for a new cover plate with an accessible focus ring for the similar Logitech C270. I modified that design as follows: * The focus ring required a "keyed" interface to the camera lens. * I added ridges to make the focus ring easier to turn. * I made the overall design thinner. * I used 2mm socket head cap screws instead of countersink screws. The base, the part that attaches directly to the camera, remains unchanged but is included here for completeness. I've also included a Fusion 360 file based on the STEP files from the original design.
