What is Flattr?
Flattr is a social micro-payments system that lets you give (and receive) money for the things you like online.
For Thingiverse users, this means you can sign up with Flattr to give money to the creators of designs that you like.
For Thingiverse designers, this means you can sign up with Flattr to receive money for your awesome designs!
Flattr is different from PayPal and other systems in that you pay a fixed amount each month - that money gets divided up among all of the people you flattr!
