OctoCache

prusaprinters

A container I originally designed for geocaching but it also made an excellent dice box gift to a friend. There are spots to insert magnets in the bottom so that the OctoCache can be magnetically attached to metallic surfaces. This was originally to allow for more hiding options as a geocache, however I've found that it works well for connecting two OctoCaches bottom to bottom as a fun dual container (like a dual dice box). In the model files there are two different versions. The normal one was designed for 5 x 5 mm magnets (actual size was 4.8 x 4.8 x 2.8 mm). The second one, denoted with BM, is designed for bigger magnets (5 x 10 or actually 4.8 x 9.4 x 2.8 mm) if you need more magnetic attraction. The threading on the lid can initially be a bit tight, but working it in a few times will make it nice and smooth. Since I've printed out a number of these I also designed a tool for working in the lid threading (the stl for that is also in the model files).  Recommended Settings:I printed these with mostly fairly standard settings on a MK3S+. The one tricky thing is layer height. For the threading to work well you'll want a small layer height, however that's only needed for the threading and is a waste on the rest of the cache. The solution that I used was to use the variable layer height feature in PrusaSlicer. You can use this to manually change the layer height to be smaller (0.1 - .05 mm) at the threading and larger for the rest. Remember to do this for both the threading at the top of the container and for the threading inside the lid. However recently I've been experimenting with the adaptive button and I've found that to work well if you don't want to set it all manually.  I've uploaded a gcode file with 0.10 mm layer height on the threading and 0.20 mm layer height elsewhere.
