Suggestions for fast printing giveaway prints for demonstration (no replies)

I am demo'ing my MendelMax at the end of the month at a local Comic Con (Wyvacon) event. Does anyone have any suggestions for fast printing models to use as giveaways? I already have these planned,

Jigsaw Pyramid - [www.thingiverse.com]

And I have printed a whole family of these trilobites, [www.thingiverse.com] to have on hand to show the potential. Of course I will have a couple Yoda busts hanging out.

Any other suggestions for demo-worthy models?

Thanks!
