Extreme Spool Holder Hub

thingiverse

After wrestling with various filament spool sizes, I'd had enough of those tiny spool hubs and decided to create one that's ridiculously adaptable. Since I had a project waiting in the wings, I didn't want to invest too much material or printing time into the new spool holder. That's when I came up with this design. I'm genuinely proud of it because it works seamlessly with most included bolt/nut combo holders that everyone already has on hand, yet requires only a minimal amount of print time.
