Cool to see 3D printing incorporated with Playmobil.
I use Maya to create my models, and am looking to build some cool steck-pieces:
* the infamous 4 way connector
* a wall with built-in fireplace (the large medieval kind that are practically big enough to stand in)
* a spiral staircase
There is a place in down-town Chicago where you can bring in your models, and they'll print them out for you.
Also, if you are looking to smooth the "rough" texture of the models, you can wipe them down with a little bit of nail polish remover, though that does make them a little glossy and you might lose some details.
