To be a NovoMaker advocate, I can see this as a casual user [in the future] using this to go "Oh! I need another napkin ring! I'll print another up for a buck!" and go to their favorite napkin ring designer's page on NovoMaker's site to get what they want.

I personally have feelings which are parallel to printthis, but I do see the market, here. Time to make some awesome napkin rings!
