Filament holder

This is a holder for the filament on your Anet A8 (also compatible with other 3D printers). It fits two bearings with a diameter of 22mm. It is very robust (ABS) besides the knobs. They didn´t break until now but they will probably do so in the future, so keep that in mind if you want to print it.

This is my first upload on Thingiverse so please tell me if I could do anything better.
Thanks.
