Extreme Spool Holder Hub

thingiverse

After dealing with several different filament spool sizes, I had it with the silly small spool hubs, and had to make one that was on the extreme side of adaptable. That said, I had a project I needed to do, so didn't want to put a ton of material/print time into the new spool holder. This is what I came up with. I'm pretty proud of it, as it works with most included bolt/nut combo holders that everyone has already, but takes a short period to print.
