This spindle mount takes the "quiet cut" spindle supplied by shapeoko.
I Made a stronger version now: http://www.thingiverse.com/thing:439283
Its thick and strong/rigid enough to be a permanent mount for the spindle or at least to hold the spindle while you cnc cut a spindle holder of your own!
Uses M5 bolts and nuts
Files are STL in mm for direct printing, also included an Autocad Inventor part file
