Mendel OpenX Carriage Bling2

This design improves on the last Bling Carriage by:
(a) adding captured M3 nut cavities for the tensioner(s)
(b)Adding some extra space for the belt to pass thru!
(c) most importantly!, on the non-tension side, add a flex member to ensure top+bottom bearing contact (reduce wobble about the x-axis)

This is ALSO a drop-in replacement for the standard mendel x-carriage. It is is inspired by Buback's OpenX Carriage with the following mods:

1. Integrated belt tensioner
2. Fan mounting
3. Some silly features that I think look somewhat artsy/blingin.

The intent of the design was to incorporate the 40+mm square space to fit larger profile extruders, while giving the carriage some steez.

I included only the full plate. I'll try and put up the individual pieces later. Hopefully you like it!
