Elna Bobbin Winder

My mother's sewing machine had a broken bobbin winder. The sewing machine is discontinued and the part for it is expensive. Why not print one? I said. The STL files contain the model for the original part (with narrower round little columns) and my improved part for sturdiness (rectilinear column type things).

Printed with PETG @ 50% on an Ender 3 Pro. No supports needed. Can post photo if there is interest.
