Double Klein Bottle Remix

I love the wireframe Klein bottle design by Gnietschow! I actually had two failed prints that I didn't have the heart to toss - and they gave me the idea to print a Klein bottle feeding through another Klein bottle.

This object is great for Nerd Sniping (https://xkcd.com/356/). How does this double klein bottle topographically differ from the original Klein bottle?
