Monoprice Maker Select X Axis Upgrade

I was rebuilding my Maker Select V2.1 and realized that I could move the x axis forward and backward by about 3mm. Which is bad, and the only way to tighten it was to tighten a grub nut that was behind a metal plate, a bar... and several other pieces of metal...

So I designed this to replace it.

The rods are completely supported and wiggle free, in fact you have to force them in a little, I just torch the inside of the holes for about a second and then push them in, and they fit perfectly!

Built in upgrades:
Dual Z Endstops
Fully Supported Rods
Screws in places you can get to
Reuses what I felt was good enough

Needs Work:
The X Limit Switches a little early, so you cant get the full bed, but this will be fixed as soon as i get a computer again.
Belt Tensioner, no way to currently tighten without removing the belt
Bigger hole for the idler, its a pain to put on
Belt mount to the extruder assembly needs to be offset to f
