Drill Spool Winder

Threaded spool holder with 1/4" universal hex steel full length shaft.

This model has been remixed dozens of times. I have been using it for years in it's broken design state. I have remodeled the entire thing in Fusion 360 to fix the printing half moon gap that has been at it's base of the thread. This design flaw made it easier for the threads to snap off from the base. Some users have tried to make the shaft go full length, but it didn't help. Not sure which program they used, the model had tons of broken polys. 

This design works. I have attempted to force a failure testing strength and it has passed. 

Print 0.2LH or smaller, 35% Cubic infill, 6 walls. I used ABS, anything will work. Use as long of steel hex you can find, I use a 12" length, so I can steady the other side of the spool from the drill.
