This here is the Wrist Rocket. Handy for packing a punch in a small package. It comes with a 5mm port that will attach to 5mm hardpoints. Designed with TF Armada Figures in mind (First Edition), this should fit any voyager, but should be a great fit for Deluxe figures with mounts on their arms (or elsewhere). Pegged pictures in preview, see Shapeways default for HP mount picture.
I also have a pegged version available as well.
Strong and flexible materials recommended.
