A small geocache container designed to hang from a tree with a zip-tie. V2.0 sports a knurled base, and is shorter overall, ideal for the 1-1/4 inch width logs. The walls are slightly thicker which makes the inside of both the top and the bottom much cleaner with the slicer I'm using. It allows for two full perimeters on the external and internal walls which eliminated lot's of stray strings inside. V2.1 has several minor improvements including slightly thinner walls.

(PLA is biodegradable) Straight out of the printer, the container is not very water-proof, so I used a small paintbrush and some acetone on the outside of the top portion to plug up all the little holes. This works better than I imagined, and dries back to hard plastic fairly fast. Make sure your work area is well venerated! That acetone can be nasty stuff. If you have problems with the top half detaching before the print is complete, you can print an extra wide skirt right up against it.
