Remix of Makerfarm i3v Y-Axis End Plate for 8", 10" & 12" with Belt Tensioner

**Update 2/3/2016 Major Rework** The dimension for the 8" i3v should be correct now since I received the dimensions from Colin Farrer the creator of the Makerfarm i3v series. I also changed the way the ledges work so I could vary the heights which should make it stronger for the 12" i3v as well as the 10"

In the openscad file the following variables you may want to change.
First set the variable i3v to the size machine you have, either 8, 10 or 12
**i3v = 10;**
