History

A few people from Hamburg started to 3D-print and wear cat ear headbands at EH20 which lead to some "can I get one, too" reactions. They continued at GPN21 and cccamp23 with a spreadsheet-based ordering system. At camp, three 3D printers were operating more or less non-stop, but weren't enough to fulfill the demand.

The camp got some more people interested in the topic of printing cat ears and two of them pre-printed a lot before the 37c3. But even 1500 cat ears were sold-out in the first two days. So demand is high, let's disrupt gender stereotypes!
