The original design by @Stiggan2k is great, and the chains work amazingly, however I found was the part that attaches to the former extruder motor plate does not fit my Ender 3 Pro. It seems like the Ender 3 Pro has a different sized plate as the screw holes doesn't match up.

I split the model using Microsoft's 3D Builder, and extended the model so the holes (hopefully) will match up. Haven't found out how to modify mesh models with Autodesk, so forgive the noobness of this remix.

All credits goes to the original designer.
