Remix of the very nice match case. Designed to be used with any standard bottle cap. I'm printing these in ABS with 100% infill. With a proper bottle cap these are completely water proof.
I remixed it with a place to mount two magnets. So that this can be used as a geocache box that can be fixed to any magnetic surface.
You find my version with and without text. The text reads: "geocaching.com - Please, do not remove"
I have also made a small "log holder" to make it easier to insert and remove the log. The solid log holder should be printet with Cura's "no solid infill top and no solid infill bottom (unchecked) and "Spiralize outer contour" checked.
Or any strong round magnet that is 10 mm diameter and approx 4 mm thick.
Secure magnets with silicone, sugru, Tek7 or something similar. A glue that can survive the wear and tear of weather and shifting seasons.
