About this 3D model

The concept is a rotating tool carousel that intersects just enough with the build volume to present a tool to the robot's arms. This way you could automatically change filaments or switch between completely different tools (dremel, plotter pen, etc, etc) . See the instruction page for details on how it works. . This is, of course, just an idea at this point. Please, feel free to run with it if you feel ambitious! :) I have included an openscad file I've been using to visualize the geometry.
