From the preview:
We put together some 3D renders to show each different weapon and equipment option for the Terran Medium Mech. The arms will be in 2 pieces so you can easily swap just the forearm or gun around, so there will be more options for poses. Also, there are 2 different leg posses, you can just glue the leg piece right into the torso.
I'm getting the 3D prints done now, I will probably have them late this week or early next week. I'll post photos as soon as I have them!
