Ring Geocache

I designed this cache container to be placed in a holder, in my case a wooden shoe :-) , that is hanging about 3 m high in a tree. People can search a stick from nature and stick it through the ring to get the cache.

I designed space for an o-ring at the top of the cap to make it water proof.

The Fusion 360 file is included so you can change the design.
Please share the remix if you improve it.

And if you print it please post a make, i really appreciate this.

Happy printing, happy G
