Hictop Perfect Spool Holder Prusa I3

This is a direct replacement for the top of the acrylic hictop printer. 3dp-03 and several similar models like the 3dp-08 among others.

It utilizes an 8mm shaft with 608zz bearings glued on both ends. I actually did notice an improvement in print quality after installation. There is next to no force required by the extruder to pull filament due to the bearings and inserts. The 2 inserts fit most standard filament rolls. The inserts have lips to keep your rolls from coming off. It just works,
