adjustable spool holder with low friction

This is a spool holder designed for the anet A8. it goes on a 8mm threaded rod and is locked into place with a nut on either side to hold the spool. it utilizes a 608ZZ bearing on both ends, and has three prongs which ensure the rotation is even between both sides.

this fits most spools it was designed with Proto-Pasta, E-sun, and hatchbox spool diameters in mind but will fit most others that fall into that range.
