The file 'Scotch Tension Spinning Wheel Bobbin – No Supports 3D Printer Model' is (stl) file type, size is 5.0MB.
A lightweight copy of a wooden spinning bobbin from a spinning wheel, with some fancy spokes.
Comes in three parts, the axle prints horizontally for strength, none of it should need supports. Recommend gluing with a plastic weld such a dichloromethane for a proper wicked-in joint, but CA or epoxy will do, it's not exactly a load-bearing part.
No idea if it will fit any particular spinning wheel, or if these parts are standardised, but the V-pulley wheel is OD77mm, the smaller wheel is OD60mm, the overall length of the shaft once assembled is 116mm, and the hole is 7mm.
