About this 3D model

This thing is a derivative of:The "IrisBoxRing" J_Hodgie's Iris Box v2 http://www.thingiverse.com/thing:5589andStargate by GlitchThe Stargate was almost the perfect size. I created a cylinder to strip off the little bumps on the Iris Box Ring and combined it with the Stargate, scaled up 2%.Unfortunately, while OpenSCAD rendered this thing (as per the picture), I couldn't get it to actually generate the resulting STL file. Maybe you can?
