This is a spool holder for the Afina H480 Spool Holder, it has a 20mm bar with 30mm flanges, and holds spools up to 80mm wide. It fits in all dimensions on the Afina bed.
Remove the four screws on the right side of the printer along the vertical bar, and replace them with four M3x12mm CSHS (countersunk cap screws) or M3x16 bolts of any non countersunk nature if you are using the not countersunk model.
Best of luck to anyone out there with these printers still running as a main printer over 10 years later. If you need any support with the printer or this model just send me a message on printables.
The author marked this model as their own original creation.
