I made this very useful threaded container that is really good at holding things like toothpicks, cotton swabs, crayons, and anything else you can think of. I made two sizes, one for 65mm toothpicks and cotton swabs, and one for 100mm toothpicks and other things of that size. I also made holes on the top of the cap so toothpicks are easy to remove as seen in the video below. I think the threads work very nice on this design. This design is also used to store filament purge. Happy printing!
