Anet A8 spool holder

These designs help get the spool holders axis of rotation to the center of the spool so it doesn't vibrate around when printing and lessen the resolution capability of your printer.

These two designs are ONLY for spools with an inner diameter of 54.8 or 54.9mm. They fit like a plug and have an 80mm diameter, 2mm thick flange on them. The spools I buy are one of these sizes (check both sides). I purchase HATCHBOX PLA 1KG spool, 1.75mm.

The center hole is 7.8mm which fits the M8 150mm threaded rod that comes with the Anet A8 for the spool holder. This rod fits snug, so spin the printed designs onto the rod, and place a nut on the outside of these plugs on the rod so it doesn't spin the spool to the edge.

You need to print 1 of each or 2 of the same, you need 2 plugs..

Print with the 80mm flange side down
