Filament guide for Biqu B1

Filament guide for Biqu B1 3D printer It uses a Ø10 x Ø26 x 8 mm ball bearing (code: 6000 for SKF, NSK... bearings brands), 2X M4 x 16 mm bolts and 2X M4 nuts. To fix it to the printer I used two small pieces of double sided tape from 3M. I used plastic bearing from Igus, that is why the bearing is white in the pictures. But you can use any steel bearing, since it has the same dimensions above. (I belive that you can print your bearing too, but I didn't tried yet) Maybe some horizontal expansion may be necessary to adjust the pulley and pin to the bearing.
