Alternate Prusa Bar Clamp (experimental)

I got tired of having unpredictable positioning of the rods when tightening the bar clamps while squaring up my frame. This new design allows the washer to fit square against the clamp sides, while a smaller set screw allows independent securing of the rod below.

I know, its pretty ugly, but I'm a total noob with openscad. Maybe someone else can craft a sexier derivative!
