Shutter style container. It was made to be assembled without any nuts and bolts. Parts are supposed to click into place. It is very much a work-in-progress, and the end goal would probably involve adding a spring to keep the shutter closed by default.

The bottom of the ring, and the container part are both threaded, to allow for easy attachment.
I also made an alternate color print that looks more friendly and a little less like an IED.
