I was trying to think of a simple unit that hadn't been remodeled yet (I know I've seen a Peewee, Zeus, and Flash before. And I think the Stumpy is also new in CA) and eventually decided on the Hammer. So here's my first attempt at an original model using this Wings 3D (finally got the hang of it, I mainly use to cut and paste pieces of TA units in Rhino).

I like how the top cannon part came out, though I seem to recall that the Hammer seems to open up the ends of the cannon when it fires? So I guess I'd have to split it in half. Also the feet are weird, I gotta work on that too. Let me know what you think!
