Hello, great design I really like it !
The knob is killing my Printrbot, could you make a handle that doesn't vibrate the printer so much, like a hexagon or something ?
Also I'm having a problem with the scaling, I printed the short screw and the short clamp, but they don't match, either the screw is too small or the clamp is too big, the threads printed fine but they don't match each other and the screw is just going freely inside the nut .
Also the protector cap is too big so it seems to me that the scaling of the short screw is a little smaller ...
Would be nice if you would do same version but with actually a M8 screw and nut, that could be really used as a clamp, this one is just a funny toy I thing !
