Oh yes. I did. I had to make this.
Not 100% happy with the way the boots turned out, but this was the best I could do with the reference images I had (all 2 of them).
Fun fact: The animators took the time to make the helmet on this thing properly. It fits almost perfectly, and the respirator goes right over the nose and mouth.
I know this because I had to use a screen-cap of Pinkie as a model for the rest of the suit that couldn't be seen.
I should make a Geiger-counter saddle bag for this...
EDIT: there WILL be a tf2 spray for this soon!
