Plain Nut for Universal Filament Spool Holder Gen 2

I've been using PurchenZuPoden's Gen 2 Universal Spool Holder for a couple years now and always thought the nut was a little on the over engineered side. (Sorry.) I always just spun it on and off rather than using the cam lock. Mine was starting to fall apart - one of the screws had stripped out and another was on it's way. I liked the size of spool it could accommodate though, so didn't really want to go to the Gen 1. So, here's the result of a hack job on the Gen 2 spindle. I liked the two-tone look of the old one, so printed this one with a filament color change at about 3mm.
