The MGN12 Linear Rail Precision Motion Kit replaces the Y axis motion system on the Creality Ender 3 Pro, Ender 3 V2, Ender 3 Neo and Ender 3 V2 Neo.

Traditionally found on high-end 3D Printers, MGN12 linear rails have tight tolerances, low friction and require minimal maintenance. The rigid stainless steel rail and ball bearing guide block improve accuracy and offer remarkably smoother movement. Mounted atop or the sides of V Slot extrusion (depending on kit), it also eliminates concerns of poor machining that can otherwise impede linear movement.

This is in contrast to the stock Delrin v-wheel rollers used on Creality 3D printers. A POM plastic that significantly deteriorates over time, they develop flat spots that bump and shift as the heated bed moves. This creates inconsistencies that reflect in the printed object. V-slot extrusions which aren't machined perfectly straight will further accelerate the wear and tear on wheels.


MGN12 Kit Features

  • High Positional Accuracy: Linear rails are extremely stiff, producing far less flex than other solutions like v-wheels or linear rods. This ultimately reduces backlash and ringing artifacts that will yield higher quality prints.
  • Long Life: Comprised of all metal components, these are extremely durable, experiencing little to no wear over time. Compared to hard plastic v-wheels that degrade from repeat use, a properly lubricated linear rail will continue to offer high performance for the life of the machine.
  • Low Maintenance: Machined from hardened or stainless steel, MGN12 linear rails are resistant to oxidation and corrosion. After being packed with grease, they have a low friction coefficient that greatly decreases wear on parts.

Fantastic product and a fantastic service


I love the products from gulf coast. Great quality and has produced better quality in my prints


Install was easy and does what it needs to!


A little tricky to get the dual rails lined up but once you get it. Works awesome. Customer service is phenomenal
