Simple and easily printable bull ring. No 3d printers were harmed during the design process.

This animal-based ring is part of the collection Ear Rings.

I've uploaded the STL file for sizes from 5.5 to 11.5. The sizes correspond to the USA and Canada standards, but here you have the list to know the diameter if you don't know your size.

Size - diameter (mm) 
5.5 - 16.10mm 
6 - 16.51mm 
6.5 - 16.92mm 
7 - 17.35mm 
7.5 - 17.75mm 
8 - 18.19mm 
8.5 - 18.53mm 
9 - 18.89mm 
9.5 - 19.41mm 
10 - 19.84mm 
10.5 - 20.20mm 
11 - 20.68mm 
11.5 - 21.08mm 

IMPORTANT: as the ring size is not very big and every printer has different settings, the diameter could be slightly different when printing it. Be careful!
