Tall M42 Rear Lens Cap (Fits Meteor 5-1 17-69mm f/1.9) Cine/PL-style

This is a tall M42-screwmount rear lens cap styled after caps paired with PL-Mount cinema lenses. It was designed to fit a Meteor 5-1 f/1.9 17-69mm 16mm film camera M42-mount lens (typically found paired with the Krasnogorsk-3), which has the deepest rear protrusion I have come across - that said, this cap should be suitable for just about any M42-mount camera lens, and could look pretty nice on your cine-modded Helios 44-2s and whatnot.

This cap should be printable right-side-up or upside-down. I used PLA but other materials should work.
