FM12 Gas Mask Lens Cap System

thingiverse

I've combined the functionality of my previous pepper-pot caps and blackout caps into a single design for my FM12, incorporating the best features of both. The new caps snap onto the outside of the FM12's lenses, while the black-out caps then screw on over them, creating a seamless fit. This design works incredibly well! I'm impressed with how it turns out. UPDATE: I've added another version of the inner cap that simply consists of the threads, perfect for those who don't want the pepper-pot look by default. Additionally, I might create an updated outer cap with pepper holes in the future. NOTE: When printing with PETG, you may need to scale the X and Y dimensions on the outer caps by approximately 1.0025 to achieve optimal results.
