Tension Belt/Ratchet Strap Winder (Spanngurt Wickler)

Insert 10mm is for an 10mm drill chuck

Insert 13mm for an 13mm drill chuck

I recommend petg because it has very good layer adhesion.

3-4 perimeters should be enough. I took 20% infill and it works well.

V2 now available the only change is a stop now so the insert doesn't fall through.

Now with a Handcrank !

its designed to be a slightly press fit, but if its to lose apply a single drop of adhesive oder scale the knob down to about 98%
