Overture Filament Spool Winder Bolt Axle

cults3d

With the original version of this winder I was worried that the stud where the drill attached would be to fragile and break off. So I modified it with a hole to put a 3/8" bolt through. This version also uses much less support since the stud isn't attached. The hex hole where the bolt head sits is a bit tight, but it will press fit if your printer is well calibrated. You can pick your bolt length, I used 1-1/2" because that's what I had on hand. I would suggest using a washer and a nut, as shown in the pictures, so it doesn't come loose.
