Anet A8 Spool Holder 52mm/57mm

thingiverse

My spool holder for the Anet A8 works flawlessly with spools featuring 52mm or 57mm diameters - the two sizes I've worked with so far. To attach it to my printer, I utilize the M8 threaded rod that comes equipped with the device. For mounting a 698ZZ bearing is required. I manufactured mine from PLA using 0.24mm layer settings on the A8, which took approximately 50 minutes each to complete. The central hole displayed a slight undersize due to my printer's limitations; hence, I employed a rotary tool to refine the inner surfaces and make minor adjustments to its size. When installing the bearings, I relied on a screw, nut, and several washers for pressing purposes. To facilitate the process, I also warmed up the part using a hair dryer to soften the material slightly, although I'm uncertain if this step is truly necessary.
