Filament roll holder, 20x20 40x20, CR-10

This filament roll holder has been specifically designed for a CR-10 printer but could be used on any printer using 20x20 or 40x20 extrusions. I designed this as part of a stand alone kit for the CR-10 as the stock roll holder is mounted on the control box.

I have included bolt holes for the side of the extrusion, but these arent really necessary, 2 bolts in the top work fine. It uses the existing tube on the CR-10 filament roll holder, so if you dont have that youll need to make up your own.
