Canadian Production Wheel (CPW) Bobbin

Model of a CPW's bobbin. There are two different sizes included. One is the same size as the existing bobbin. The second set (file names start with 'bigger') are designed to be as big as possible on the flyer.

This is printed as 3 parts to get the best quality, then all three are joined by CA glue. If you have a good quality printer the higher precision shaft gives a tighter fit.
