Logitech C310 Focus Ring and Coverplate

thingiverse

[EDIT 2019-09-29] Added a few more photos to help illustrate the disassembly and assembly process. I'm using a Logitech C310 webcam in conjunction 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 be able to adjust it again more easily should the need arise, and I found a design for a new cover plate and accessible focus ring for the very similar Logitech C270. I modified that design as follows: * The focus ring required a "keyed" interface to the camera lens * I wanted to make the focus ring easier to turn, so I added ridges * I wanted the overall design to be thinner * I used 2mm socket head cap screws rather than countersink screws The design of the "base", the part that attaches directly to the camera, is unchanged but included here for completeness. I have also included a Fusion 360 file which is based on the STEP files from the original design. Thanks to the designer of the original model!
