This is just another filament holder, with the option to mount it anywhere through the four holes.
What you need for the filament holder is a bearing with an inner hole diameter of 8mm
and a thickness of 22mm. I used an outer diameter of 22mm. it will certainly also work with a thinner one if you adjust it accordingly with washers, for example.
You will also need m8 bolts and m8 nuts.
Enjoy :)
