Ender 3 Rail insert

This is a model of the insert for the Rails on the Ender 3 pro. I have the Ender 3 Pro and this is what I used to design this. I can make it fit more snug if requested.

It can be modified to your desired length in whatever design software you are using.

Rotate it so that you don't need supports, that is assuming you are printing this just to test fit it. You may need supports for this depending on what and how you use it.

This can be used for making your own parts.
