Fits Ender 3 on others, haven't checked but should work. It depends.

The model consists of 4 parts. Choose which wheel you want to use. With or without bearing. Use a vice to insert the bearing. Bearing dimensions below

Folding order:

The arms are pressed in. It's best to use a vice

Now it is enough to mount it (probably the easiest way will be to the screw holding the roller at the extruder). I hope it will fit as many printers as possible
