The file 'Snap On Spool Roller 3D Printer Model' is (stl) file type, size is 1.9MB.
This is a spool roller I designed after seeing a few that were fixed in place or required other means to attach them to the printer.
This will fit Cocoon / Wanhao printers with a top bar measuring 49mm top x 50mm front. It uses 608 bearings for the rolling points like many others, but the clamp part will "snap" fit onto the printer frame. The clamp width allows my filament guide to fit in between if you need one. You could also just print the side frames and sit the rollers on a bench or cabinet top.
