@tug I was reacting about your "You are kidding me right".
I know several projects where someone sells a finished piece, but offers every information for other to make it for free !
For example Makerfr's 3D printer : he sells the frame of the 3d printer, but all sketches are available for anyone to make their own !
But i fully understand and respect your will to get paid for your work !
(and i think your unit is impressive and price worthy !)
