Playing with kids is any good dad's hobby. I do that every day as well as games and movies. It's really funny in retrospect how we began to talk and how much we have in common.

My friend down the street took two 6x6 3D's and reframed them, wrote new code to make them 24x24. Almost 48 hour+ print times for stuff 5 x16. Once they can really print at a speed that is worth it, I'll pick up some of the metal printers. Too much can go wrong in that amount of time with this many kids.
