These 6 holes will have balls glued in. The holes are slightly oversize for a glue bond and a vent hole has been added so that the balls will not piston out due to a trapped air bubbles.These devices are designed for reproducibility of placement. Precision is not so important as long as the location of the three parts in the grandmaster_kin_assembly.SLDASM are not interchanged. These 3 parts and their positions will be labled.
