ah, I see what I was missing. It's a tire over a stud to form the wheel. Very clever.
Some nice variations here. The scout version is my favourite.
Like you, I think I may include a few of these in mecha scenes for scale purposes.
I like it

This is a very impressive array of variants, I especially liked the air-defense versions. Thanks for making these, its fun to see other ways I could have gone with the design.
