Summary

Egg Box

Waterproof box in form of an egg.
The upper and the lower part can get screwed together.

I printed the eggs in ABS and used a soft PLA for the o-ring which helps sealing the egg.
Both parts of the egg I printed with the tread looking to the builder plate. For the lower part I used support material which get cut off after the print.
After printing the o-ring gets screwed on the lower part of the egg.
