The ring sizing set in millimetre circumference sizes!

Accuracy of 0.01mm sizes includes 44 to 70 millimetre.

Made with 2 separate holders for te small and big sizes.

When you first screw on the cap be cautious to move it back and forth until it will slide easy.

Don't tighten it too hard it's not necessary and the PLA will eventually break.

I printed everything with PLA (holder is PLA matte and rings in PLA basic).
