Flashlight cover for snorkeling

The best material is SLA resin or PLA with 100% infill (set high number of perimeters).

Print the middle part with flexible filament, glue everything together with superglue. Use a color change or cut the bottom part to make it transparent.

The best transparency can be achieved with SLA transparent resin or non-3D printing method.

Treat the thread with silicone grease, don't forget to use a proper sealing between parts. I suggest using O-rings but soft gaskets also work fine.
