Filament Spool Holder

This is a spool holder. It is a screw type, but the screw it the smallest possible size to still fit over an M8 nut. This makes the print time much quicker. the screw length was designed to be about the correct width to get 2 spools on a top mounted spool holder on the prusa clones (such as Anet A8). Although it can fit on any holder with enough legnth and an M8 screw.
