The gears of the K8200 extruder often produce dirt, which then rains on the heating bed. And it only gets worse when the gears are greased.
There are already some solutions for this on Thingiverse - but I still want to be able to turn the gears by hand. This design is easy to install and easy to remove.
I put some drops of hot glue on the mounting part. This prevents it from rattling when the printer is making hectic movements.
Two M3 screws are needed to connect the two parts together.
