Creality Ender 3 X Axis Linear Rail Mod



Just a very simple X Linear rail mod using an MGN9H rail, Y offset is increased slightly due to the rail carriage but it isn’t by much just 7mm.

You will need to file or grind a small bit of material away from the Extruder cover mounting lug where it catches the bottom M3x6mm mounting bolt.

I bought a longer rail 330mm because i don’t use the endstops, most suppliers will cut to any length you need though.

You don’t need any additional hardware other than the rail itself and a few M3 T-Nuts and some Bolts:



1 x 320mm long MGN9H Linear Rail – Aliexpress
8 x M3 T-Nuts – Aliexpress
12 x M3x6mm Cap Head Bolts
2 x M3x25mm Cap Head Bolts
3 x M3 Locknut
1 x M3 Washer

And That’s it.
