Spool Drill Winder

A simple spool winder that can be operated with a standard drill. If you use it more often I recommend to get a metal drill bit. EU: HOP8x89, like Wera 840/4US: 5/16" long bit, should work as well Alternatively a printable adapter is supplied as well. Printing it in stronger materials (like PETG and above) is beneficial. All parts can be printed flat without supports for optimal strength. UPDATE: Version 5 (18.12.2025)extended screw thread by 10mmthickened printable drill bit for tighter fit
