This Filament roller is for the I3 Mega-S and the upgrade kit.
Started remixing and ended recreating it from scratch in Fusion 360.
It is a shorter version, as my filament spools only have a maximum width of around 6.5cm, the roll has 6.8cm.
You will need two aditional 608RS ball bearings and two M3x8 screws, e.g. this one at amazon.de
If you like, buy me a good german beer :)
