A small jar to store some goods. It comes in three sizes: 15, 20 and 25 mm jar height. After printing you should screw the jar and lid back and forth and clean the thread with a tissue a couple of times, in order to grind the thread in and make it rotate smooth. The longer you screw, the smoother it gets. If you can't turn the lid, try printing it just a touch bigger.

jar_15 is the smallest and will fit well in your pocket ;)

Update 2021-04-01: I just uploaded the blendfile. As a goodie you'll find an additional lid with an engraving and a jar with honeycomb pattern in the blendfile.
