This is a very small screwtop container.

I use it to store small screws. Works also very well to carry a bit of hand creme.

Print with 0.1mm (or better).

And please don't use supports. If you do, you'll spend a long time cleaning it out of the threads ;-)

This design uses the lovely OpenScad threads library by Cuiso for the screws.
