Spool Holder - Universal - Self-Centering

Universal Filament Holder. This allows the spool to spin uniformly due to the self centering feature. Saves a lot of material based on other models I have seen which take hours to print. Threads might be a bit tricky based on your part cooling (The more the better). They worked for my Anet but if for some reason you have an issue just lower your flow rate to ~90% and try again.
