These containers are useful for all kinds of outdoor activities. You can use it to transport batteries, bring dry matches to their destination, store salt, pepper or herbs for cooking or do many, many other things. It is also possible to scale the containers and thus create storage for hearing protection or tablets if necessary.

--– Printed O-Rings (TPU)---

I do not recommend using self-printed TPU O-rings. In my tests, these performed worse than original ones. But they are still better than no O-Ring. But only if you use very very soft TPU! I have 2 versions. One O-Ring to put into the lid and one for the outer O-Ring version. (Keeps the threads dry too). Don´t combine both O-Rings because that might reduce the sealing capability!

--The POWER of Scale!--

You may scale the Container to your needs! For example bigger for more stuff or smaller to transport some pills, ear protection or sth. else on your keychain. try it out yourself! But keep in mind that the container needs to stay round and the needed O-rings will change their size too (if you print a version with O-Rings). Also watch the printed perimeters in your slicer! (at least 2 will be needed to giv it protection vs. water!)

Inner Volumes as base to scale the container:

Large: 69 mm hight x 19 mm diameter.

Small: 36 mm height x 19 mm diameter.
