Hatchbox Spool Adapter for m8 (8mm | 5/16") Rod

thingiverse

I made this so my Hatchbox spools fit onto the spool holder that came with my Anet A8, but it can be used to put the Hatchbox spool on any 8mm rod. You will require 2 of them. I used a nut to keep it in place as you can see in the pictures. This thing may work for other brands of spools, but I have only used Hatchbox so far, let me know if it works for other brands.
