Contact Lens container

I decided to redesign Jijou thing because of problem with screw thread print in it's original model. It is so small, so on FDM it prints bad regardless of what resolution i'm set. I tried with 0.2 and 0.1 - nothing changed.

My design is a copy of Jijou design but with slight difference in demensions and much bigger thread that prints very well on my Prusa i3 mk2s. Also it has a little smaller space inside of container and thicker walls than in original.
