This is an adapter for Creality Ender 3 to use a spool holder on the side of the printer. All parts are ready to print.I took a few parts and put together in order to make it possible and easier to me. For the spool holder you have to use 2 bearings 608 (20 mm outer and 8mm inner hole), I took mine from a cheap one dollar finger spinner, one 8 mm screw 170 mm long (17cm), 2 X nut of 8mm with nylon locker (better but not necessary). Here are the links from here I took the parts to remix.
