I surrender! After testing I've been unable to locate a current source of 3D print production that can beat Shapeways on pricing. Customer service and turn-around time are another story! I'll be turning on a limited set of Battery Holders, Mods and Mounting plates. I have tested the DNA40D and it fits in the mods fine if you remove the mounting rails. Please read the datasheet at Evolv's website for recommendations on the proper procedure.
