Can anybody Identify what extruder body is included in this kit? I have one but am having a hard time finding mating files that support this type of extruder body. I'm guessing that it's a unique, custom design for this particular Prusa build from E-Motion tech. I'm looking to retro fit this build with a Bowden type extruder setup that uses the standard skateboard type bearings. Also - I'm designing up a mount bracket that holds the extruder body onto the flat frame to create a bowden type driver. If anyone has ideas, tweaks, or suggestions, post away. P.S. - I'm trying to stay away from the Makerbot type of drive wheel and stick to the traditional type of hobbed bolt design.
thanks - JD
