A 49mm lens cap that I made. Works great with my Sony lenses. Be careful to use this lenscap with too rounded lenses as the backside of this lens cap is flat for easier printing.
I made a lite version, see "49mm_lenscap_V3_lite.stl" which requires less force to remove and put on, it will however fall off easier.
I did some quick simulations, more for fun than to check the model:
Rafts:
No
Supports:
No
