Yes, but when we were kids we wanted to design our own weapons and toy soldiers :)
I was thinking along the lines of printing kid-designed soldiers or weapons :)
Absolutely niche (though maybe not that much niche for stuff like Warhammer 4000 or tabletop war games or whatever :) ).
A toy soldier that costs the better part of a dollar in materials, or one that costs fractions of a penny? Which one is going to provide better margins?
