Single piece Y ends for Prusa i3

These are monolithic (single piece) Y ends that I created for prusa i3. I was inspired to try this by the Lulzbot TAZ design, and I think it's pretty neat.

*Hey everybody , I've redone both designs now in OpenSCAD to be parametric. Enjoy! The -default STL files were generated for M8 smooth rods and M10 threaded rods. If you want to roll your own, you'll need the small parts (sub assembly STLs) which are included into the single-piece models and are not meant to be printed on their own.*
