eNDER 3/ pro Filament roller

Simple filament spool roller. Requires bearing 608rs which has an 8mm inner bore, 22mm outer and a depth of 7mm. Standard skateboard bearing. I bought an 8 pack on amazon for $6.00 USD. Fits standard ENDER 3/PRO filament roller. Clips on easily. No modifications. Just add bearings and clip on. Filament spool should fit right over. If it doesn't, just assemble from the sides. Enjoy.
