Wanhao D9 500 Y-axis Linear Rail guides

I've created this to add MGN12 linear rails onto the D9 500. Since the bed is so big, you're best off with two MGN12 blocks on each rail, to keep it stable - One is simply not stable enough.

You need:
- 2 x MGN12 700mm rails
- 4 x MGN12H blocks
- An assortment of M3 screws

EDIT 26/10-2020:
Following Brian Grimshaws video using my Rail Guides I've updated the description to better explain how to mount them :-)

It will take a bit of fiddling to get the two 4020 extrusions to line up
