A variant of my 18650 case (https://www.printables.com/model/554019-18650-battery-carry-case). It fits common AA batteries and unprotected 14500 Li-Ion. Closes tight and doesn't roll off the table. Body prints without supports. Lid needs supports for the roof, but make sure not to support the threads.
For the threads to work properly without post-processing, you must use a layer height of 0.15 mm or below. Tested with Prusament ASA and Prusament PC Blend.
The author marked this model as their own original creation.
