Lens cap 34mm

Spring-loaded lens cap for my Industar 50-2 50mm f/3.5 camera lens. It should work fine with all ⌀34mm lenses.

Print instructions

I made this one as I prefer a spring-loaded inner cap, if you prefer an outer one, go for https://www.thingiverse.com/thing:2133519.

Notes
The thing was designed with ABS flexibility in mind. PLA might be too rigid for this design (ie. "springs" might require uncomfortable amount of force to operate).

Post-Printing

After printing, one needs to:

1. glue the middle of the springs to the main body (the red to the blue part),
2. glue the inner walls to the body (the yellow parts into the blue one).

If one's printing the thing of ABS, then a single drop of acetone suffices as an adhesive (or rather solvent).
