FujiFilm X-Mount Rear Lens Cap

thingiverse

I needed a bunch of rear lens caps for Fuji X-Mount lenses when I picked up some lens adapters for my old M42 and Olympus manual primes. Rather than buy a 3rd party set off eBay (or pay Fuji's ridiculous prices!), I thought I'd spin up a replacement in OpenSCAD and try printing them. They are based on similar dimensions to the official caps, and I designed it with grip notches to give it similar ergonomics to the injection molded original. I've included the OpenSCAD script in case you wish to make any changes - the STL and default values in the script are for most normal lenses and adapters, but if you have a lens that has elements that extend past the mount then you may wish to increase the internal_depth value to 12mm, for instance. Finally, the text on the front is configurable, in case you want a personalized design :) Print Settings Printer: Prusa i3 Mk2 Rafts: Doesn't Matter Supports: Yes Resolution: 0.10mm layer height, 0.40mm nozzle Infill: 20% Notes: This printed well on my Original Prusa i3 MK2 in Rigid.Ink PLA (1.75mm), using Slic3r (Prusa edition). Because of the angled inner lugs and the acute front face edges, you probably want to do this at as fine layer height as possible (I used 0.1mm). The supports that I found to work best were rectilinear grid. NOTE: Make sure to rotate the model 180deg (flat face down) for printing.
