Ender 5 Y axis MGN9 linear rail adapter

A great upgrade for someone that has two spare MGN9 rails and an Ender 5.  I was able to save over 60 grams over the stock V wheels and gain some rigidity along the way. The result was a 55% increase in Y accelerations without skipping steps! 

This is not a perfect upgrade! MGN9 rails are the same width as the V wheel groves. An alignment tool is mandatory and care should be taken to make sure the rails do not twist inside the groves. I would not recommend purchasing MGN9 rails for this purpose, but if you have a spare set anyways it is a good use of those parts. 

M5 screw holes are intentionally undersized so they can be tapped for threads. 

Required hardware:

-2 MGN9 rails

-34 M3 T nuts

-34 M3*8 Socket head cap screws

-8 M3*8 button head screws

-4 M5*16 screws
