It's been a long while since I've played around with anything substantial for Sketchup and Shapeways, but I put together a quick weapon for TR Kickback. It's a fairly simple and plain render, but it was a bit trickier than it looks. TR Kickback has some weird kibble in front of his hands that interferes with the tommy-gun like disk, so I pushed it forward. I also distorted the butt of the rifle so that Kickback can still bend his elbow (if my measurements are accurate). I ditched the side guards. It's up on Shapeways for testing (as well as weapons for Bombshell and Shrapnel, if you need them).
