spool holder for 3D printers

This project contains two types of filament spool holders, one for prusa i3 3D printers and one for direct feed 3D Printers. This filament spool holder is extremely easy to assemble, just need the right screws, if you don't have metal bearings , it doesn't matter, you can print the bearing is also applicable. This filament spool holder can hang two rolls of filament at the same time, which is very suitable for direct feed 3D printers.
