UPDATE: some as yet unexplained issue cause other objects not to render in the same openSCAD file as Y2. I've created a new Y2 from the Y1 model. enclosed are net .stl and SCAD file describing this process. These are fixed stl files for mrule's thingiverse.com/thing:4893. They are not otherwise altered. If you have trouble importing these into OpenSCAD, please let me know.
