<p><i>Update</i> 2019-09-29: Added a few more photos to help illustrate the disassembly and assembly process.</p><p>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 <a href="https://www.thingiverse.com/thing:714475">design</a> for a new cover plate and accessible focus ring for the very similar Logitech C270.</p><p>I modified that design as follows:</p><ul><li>The focus ring required a "keyed" interface to the camera lens</li><li>I wanted to make the focus ring easier to turn, so I added ridges</li><li>I wanted the overall design to be thinner</li></ul><p>I used 2mm socket head cap screws rather than countersink screws<br>The design of the "base", the part that attaches directly to the camera, is unchanged but included here for completeness.</p><p>I have also included a Fusion 360 file which is based on the STEP files from the original design.</p><p>Thanks to the designer of the original model!</p><h4>Print Settings</h4><ul><li><strong>Printer Brand: </strong>Prusa</li><li><strong>Printer: </strong>MK3S</li><li><strong>Rafts: </strong>No</li><li><strong>Supports: </strong>No</li><li><strong>Resolution: </strong>0.15mm (0.20 is probably fine also)</li><li><strong>Infill: </strong>10%</li><li><strong>Filament: </strong>CC3D Silk Blue PLA</li></ul><p><strong>Assembly</strong></p><ul><li>Carefully remove the original cover plate from the C310 to expose another plate which holds the lens cover.</li><li>Remove three small screws from that plate and remove it. Keep the screws.</li><li>Test fit the focus knob to get a feel for how it will attach and operate, then remove it.</li><li>Place the newly printed base in place and secure it with the three screws you just removed.</li><li>Slide in the focus knob like you did in the test-fit</li><li>Place the cover plate over the focus knob and attach with two m2x6mm socket head cap screws.</li></ul><p>See the attached photos to see the original cover plate and the assembled version.<br>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>
