45 EUROs for all that? That sounds extremely cheap! Could it be a scam?
With Kickstarter you can never be certain until you've got your rewards delivered, of course — nature of the beast — but I'm inclined to doubt it.
As I noted, and as it even explicitly says in the campaign's title, they're not offering a bunch of miniatures for €45. You pledge €45 for a folder of stereolitography files that you then take to a 3D printer and print out miniatures from. It's good value, yes, but does not strike me as unreasonably cheap.
