Acupuncture needle box

My wife needed a portable container for used acupuncture needles that doesn't spill the needles in the handbag.

Its made with openscad, but needs some libraries, if anyone wants the source, drop me a message and i will put it up on a git.

How I Designed This

first i tried with only a anti reflow cone, but with enough shaking i managed to get some needles out, so i added a rotating cap in the cap, but managed, after some use, to remove said cap, so i made it print in place....
