C-Mount Rear Lens Cap (blank)

I tried using other numbers, but in the end it wasn't worth the time. So I just created a blank version to avoid having too many "2" caps. About the model: It's literally perfect, so good. Nice for a protruding lens where a normal rear lens cap does not work. The threading is so smooth. It screws firmly in place. I will use it for every C-Mount lens I have. 0.15mm layers / Infill: 30 / Notes: 101% scale. For me it requires slower printing speed.
