RatRig Vcore 4 filament guide ECAS remix for strength

See Dizzy Keeb's original post for more information. There is no thread on the ECAS version, so for the IDEX I just mirrored it.

 I did the modification in FreeCAD dev 1.1, and have attached the file if someone wants to see what I did.

I printed the original in a dark color, and printed the new one in an off-white (recycled transition filament). The lighter color doesn't look as nice but makes finding things much easier. The bottom of the printer is black as are the ACM sides and its hard to see much down there.
