This mount is a direct fit replacement mount to attach the Ryobi router to the Shapeoko 2 gantry. This should also work with the original Shapeoko.When printing, no support or rafts are needed. Simply print at a maximum of 0.3mm layer height (to make the piece less brittle). Infill at least 60% Break off little adhesive disks after printing. Use M4x60mm screws (from Shapeoko gantry) to tighten clamp, and M4x30mm hex screw to attach adapter to gantry. Test part printed on XY high speed http://www.thingiverse.com/thing:436295
