Hatchbox PLA 1kg spool holder

thingiverse

This was printed in my glow-in-the-dark hatchbox PLA, too. :D After purchasing a 1kg spool of filament, I realized there was no possible way I would be able to reliably have this filament feed into my printer without having bearings in it. So, I pirated some skateboard wheel bearings out of an old wheel I had kicking around, and now, it rolls! Just have to print two of these bearing holders, use two skateboard bearings, then construct a stand out of PVC pipe like I did - until you can print something better, anyway. I got two T-joints and used a 1/4" piece of wood to fit inside the bearings. It's not even the size of the inside of the bearings - it's smaller - but there's no friction whatsoever to turn the spool.
