Keyring, Sizes 12-28 mm, All Purpose Split Key Ring

Split Key Rings, all purpose, five sizes

Now here something reeeeally simple - yet (I hope) also really useful (I guess sometimes it's the most simple things are also the most useful...).

I recently decided to reorganize my spare keys, for which I simply needed a few key rings (which of course I did not have). A quick search of Thingiverse ended with some really fancy gadgets (including some really nice ones!) to be attached to the actual key ring but not what I was actually looking for, a simple ring to keep my keys together.

- 12 mm inner diameter
- 16 mm
- 20 mm
- 24 mm
- 28 mm
