Please note: these adapters require MGN12H or C rails for the Ender-3, and MGN9C rails for the Ender-5. The length required is 300mm (CR-10 coming soon). 

This kit allows you to add linear rails to your printer's Y-axis, replacing the factory V-slot roller wheels entirely.

They are compatible with MGN12H or C rails for the Ender-3, or MGN9C rails for the Ender-5 (300mm for Ender-3 and Ender-5), and require no modification to your bed plate, Y axis belt, pulleys, tensioners, or Y stepper motor location.
