The file 'Boat Shuttle Bobbins Drill Adapter 3D Printer Model' is (stl) file type, size is 1.9MB.
This is an adapter to be able to wind a boat shuttle bobbin using an electric drill.
Will work with bobbins from 91 to 115mm long.
heavily over design if you ask me but It works great and was a nice Fusion 360 practice.
