This is a "52mm Camera Lens Cap" produced by powermoss. This lens cap is among the best on Thingiverse. The main purpose of the product is to protect your camera lens from damage. It is designed to be worn without supports, making the process easier, and has threads to ensure a tighter fit. This product can easily be scaled to other sizes (for example 49mm or 55mm).
The lens cap can have a slightly loose friction fit, so be sure to attach the front and back pieces together with a little glue in the mounting holes so they don't separate. 52mm_cap_spring_std.stl is for those who may want to use the original design but want the threads that give better grip.
