Spinolution 4 oz and 8 oz bobbin with modified fitment

thingiverse

This is a revised version of https://www.thingiverse.com/thing:2751291 to match the cutout on the original bobbins perfectly. The original file features a hexagonal cutout for the nut that demands precise alignment with the nut when putting the bobbin onto the wheel. This design boasts a twelve-point cutout, making it easier to get the bobbin onto the wheel correctly. I simply opened the .stl in Tinkercad to create this modified cutout. This revised remix only includes files for half of the bobbin. You will still need the file for the other (smaller/shorter) half, which remains unchanged and perfect as is. Thanks go out to kg4iae for creating an excellent design that I've been able to build upon!
