Embroidery Card to Bobbin Winder Sewing Machine Adapter by Billie Ruben (old)

thingiverse

This tool lets you spin embroidery floss cards automatically using your sewing machine's bobbin spooler, freeing you from tedious hand work. It's a fast printout that takes 20 minutes or less, with no need for additional support. Edit: I've revised the design to feature a smaller base that mimics a bobbin, accommodating more machines, and made it taller to prevent card snagging on other parts of the machine. Happy printing!
