About this 3D model

The original filament holder that came with my printer was intended to use with loose filament (no spool). I had to design this holder for the spool that came with the new filament i`m testing, which has a 55mm tube (it can be used for spools from 54 to 57). To lower the draft, i used two bearings (22mm outside diameter X 7mm wide) Enjoy!
