I'm playing with Calvin and Hobbes inspired mutant snowmen. I like the model. I am pretty sure it won't print (the wall in the mouth is .5mm, apparently), but I'm mortified by the print price in white plastic! http://shpws.me/q1ii It is fun, but I doubt that I would have any buyers at ~$70.00!
I finally got around to checking the actual scale. I had it much too large. I shrank it down so that the mouth now accommodates standard pens (it would have originally held 3-5 pens). ~$9.00 is reasonable, I think.
