X-Axis Linear Rail Upgrade for Ender 3

Upgrading your Ender 3 / Ender 3 Pro / Ender 3 V2 to linear rail has never been simpler!

Convert your Ender 3 to X-Axis linear rail in minutes. Bye Bye POM wheels! Get a smooth & precise motion + no vibrations…

You only need a 300mm MGN12 linear rail, a couple of M3 bolts & T-Nuts, and a 3D printed adapter. The 3D printed adapter is a replacement of the metal X-carriage with extra holes to attach it to the MGN12H carriage block. It provides the same attachments/holes as the original metal plate making it highly compatible: You can use it with your stock Ender 3 but also with many other cooling mods.
