Filament Spool Holder

I have uploaded all the Inventor files as well as the assembly file.
You can now change the sizes so that it works with your spool type. The bearing should be a slight press fit into the pulley so that will have to be adjusted for you printer. The bearings used are 608 aka skateboard bearing.

Check out Base V2. If you use two of them instead of the main base then it will work with any width of spool. All parts are interchangeable.
