y belt holder vertical for prusa i3

wilson ts y belt is by default oriented such that the teeth is perpendicular to x-y plane. I made this because I'm changing out the MDF board to aluminum carriage which comes with three SCV8UU and two holes in the center of the carriage 41mm apart to attach the y belt holder.

So I modified this vertical belt holder labeled as "ytable-8mm.stl" from mjrice link to that stl here: https://github.com/mjrice/wilson/commit/15bbdde62b79b8b839b46344a24383e9eda49e3a

I removed the rest of the table
