Bobbin Winder - Screwdriver Bit

Screwdriver bits for winding floss onto bobbins, for both standard & small electric screwdrivers. Screwdriver bit adapters to wind embroidery floss onto bobbins using an electric screwdriver. Designed for use with paper bobbins (I use the Hemline ones) or this 3D printed one. Two sizes included - one for standard bits (¼" or 6.35mm) and one for the smaller bits you use in precision screwdrivers (4mm). You need one peg per adapter. We printed in standard PLA on a 0.4mm nozzle, with 3 walls, 15% infill, 0.2mm layers. Manual supports were added to support the bobbin holder, but no supports needed for the holes.
