MP CNC Rotary Tool Spindle Mount Asist type

This is the holder for a cheap Asist like spindle hand tool. I used original tool holder from MP CNC part list + Shapeoko 2 remixed parts (2 remixed + 2 original - clamps). I am also attaching 123D files to be able to change size of the holder, ,which probably could be a little bit smaller (shorter legs), but I am calculating with screw nuts...
