I wanted to keep my very first noozle, and thought about make a keyring with it, so I was thinking about what, and thought about a calibration cube, but with rounded corners to avoid being hurt.
So, here you have, a nice keyring to have your first noozle, or your most preciated.
2 versions provided, one in 20mm and another one in 25mm.
Hope you like it, I love it :-)
0.12 works great, but just try anothers
