Tetrix Spool

thingiverse

This is a spool I designed with a Tetrix four hole center. It has an outside diameter of 70mm, inside of 55mm, and the string wraps around a 172.788 mm circumference. You'll have to drill a hole in the side to tie the string off because I forgot to make one and I'm simply too lazy to go back and make one. If you like this design but you need a different diameter you can text me and let me know at 219-698-6264 and I'll happily design a custom one for you.
