This model is "ready for manufacturing". Since this is a unique model I prefer to wait until 3D printed parts price drop enough to get this "kit" straight out the printer... Some parts are quite intricate, and would probably not withstand the RTV mold creating process. This model was one of my entries for the 2008 Alibre design contest.
