Creality BLV Ender 3 PRO Upgrade MGN12 Linear Rails Full Kit with BL Touch Auto Leveling Sensor Also Compatible with 32bit V4.2.2 or V4.2.7 mainboard Ender 3, Ender 3S 3D Printer

It'd be great if the pictures were sufficient to put it together. Hopefully I get instructions on how it goes together! The material quality looks decent enough!updated! The pictures don't match the product. The x bracket in the picture is upside down from what it is in the product. This makes a direct drive attachment impossible. Additionally, the bracket on the left side was bent and didn't match up with the holes.Not worth it the hassle

Note: this only works for ender 3 PRO- will not work for basic model.The Good- if you spend hours on it , it will eventually work.The bad- no instructions makes it verry hard to assemble. Parts are made of cheap metal and feel flimsy. The rails are low quality and don’t slide perfectly.
