Frame-mounted filament spool for Anet A8

thingiverse

Compatible with even the largest of spools, this spool holder requires no hardware and attaches directly to the acrylic frame of the Anet A8. Profile is slim enough such that it doesn't interfere with the printer head when printing very tall objects. If you're looking to save filament, print on its side with the spool arm and frame clip are facing upward, such that the only supports required are along the spool arm going up to the rectangular end stop
