This is an adapter set for the Stunicon and Protectobot Car Cannons in my Shapeways shop.
This plugs into the 5mm port on the rear of Stunticons's vehicle mode and creates a 5mm peg on the vehicle. By itself, the adapter can be used as a hand held weapon. It has 5mm ports to combine with other transformer weapons. This is compatible with Combiner Wars Deluxe class figures Dead End, Break Neck, Breakdown, and Dragstrip (or similar molds like Streetwise, Smokescreen, Prowl, Break Neck, Lightsteed and more. This is not meant for use with the Truck mold combiner limbs. This would also work great with War For Cybertron Modulator and Weaponizer Figures
This is sold as a set of 2 pieces connected together. You will need to cut them to separate them and trim off the excess plastic.

This was printed and tested on my home 3D printer with PLA plastic. Depending on the plastic you choose, sanding or polish may be needed to fine tune the fit.
