I am a member at Yakima Maker Space, and I am currently making a philosophers foosball table. I hand sculpt each philosopher in clay, then 3D scan (with a Next Engine HD), model in Rhino 3D, and custom print each character. Each philosopher takes about 40 hours to sculpt and a bit of time to print. In all I will have 24 characters, 11 Germans, and 11 Greeks, with 2 substitutions. I will be posting each under CC so you can print your own if you like, with the ambition of making a full foosball table people can procure sometime in the future, if one so desired.

ABS is your best bet. Once printed you can drill out the body to fit your table rod size. 9/16" or 5/8" is most common.
