The Ender 3 V3 SE & KE are great machines but the bed is a problem in my opinion.. specially in the KE when it is capable of printing at up to 500mm/s. The factory bed has a lot of play and flex. From the front post, to the linear bearing housings, and the bed frame. It all adds up.

I have made two versions of this mod. One for MGN9H rails and MGN12H rails. I recommend using MGN12H.. but its up to you.

For those installing the rails in the SE, you will need to print the alternate rail adapter. The main plate could hit the rear post before activating the endstop switch.

You will not lose any Z build area with this mod.

If you like my work consider buying me a ko-fi ☕😊 Your support is greatly appreciated.
