Spool holder for 5 to 7.5 cm diameter quick change

thingiverse

All credits for Jadames.who made the original. No more trouble with loosen and fastening nuts, change filament in halve a minute. Problem with original one is you can't use spool with 7.4 mm diameter, because the holder falls into the spool hole. I made the holder bigger, but you can still put a 608ZZ bearing into the hole, you can use without it too. The total lenght is 101.6 mm, it still fits the original Anet A6 and A8 filament holder. If you have 1/2 kg filament spools, you can put the nut inverse and use it that way. Tested on esun, sunlu, amazon basic, eryone, cctree, anycubic filament spools.
