Anet A6 A8 filament spool spindle holder

thingiverse

I modified it to fit my A6 printer by shortening the spool size, swapping in bearings that are widely available - specifically 608 ZZ models. To keep things simple, I used the original rod and nuts from the holder that came with it. This setup works great on my A6, but it might also work with other printers of similar size. The dimensions of this custom spool come out to be 95.25MM X 30MM, which printed perfectly without any raft or support issues.
