Upgraded High Strength Winder

thingiverse

I remixed these winder shafts and knurled knobs so they would work together. I also wanted the knobs to fit VERY snuggly on the shafts so that I wouldn't have to glue them, but they wouldn't slip off either. If I need to get them off, it takes some work, but they will come off. I used some small files from Harbor Freight to smooth down the shafts and the holes in the knobs until they were just the right fit.
