I started modeling the Landing Pad in SketchUp.
I started with the battlements:
I then moved on to the landing pad itself. You can see from the side view that all the elements are raised from the base by 1/16". I'm hoping this works out once I cut them.
I also made it so the battlements can be inserted on the top or on the side of the base. (The actual War Hammer one are on hinges so they can be raised or lowered).
I'm working on the legs next.
