Bobbins for Spinolution Pollywog Spinning wheel 4oz and 12oz

This print fill will create two sizes of flat pack bobbin for Spinoloution yarn spinning wheels. Flat pack bobbins are easier to store for travel as they can be disassembled into 3 pieces. When printing you can chose what size to print the shaft design works for both the 4oz wheel size or the 12oz wheel size. Since this is printed in plastic rather than the original wooden design the bobbin itself is both able to hold more yarn and is almost ¼ the original weight. 

During the printing process for the shaft at around 14.75mm insert a pause in the print to place a metal washer (17.5mm OD with 9.25mm ID). The washer is used to connect to the magnetitic locking on the wheel. 

After printing the threads can be a little tight but if you just work it on and off slowly a couple times it will spin easily. I also run a drill through the center hole to remove and possible excess plastic.
