Featherweight Bobbin Tray
I recently acquired a Singer Featherweight 221 sewing machine, it’s just over 80 years old and yes it works. My husband who by all means is brilliant in his designs using his 3D printer has designed and made a bobbin tray that fits the metal bobbins for the Featherweight machine perfectly. This is the link to the Featherweight Bobbin Tray, the link will take you to my husbands page LGWorkshop for a FREE download of the design.
