MY FIRST EVER THINGIVERSE UPLOAD, yaaaaaay!!
2-part biscuit/cookie cutter featuring (a derivate of) the logo of Metalab, our super awesome hackerspace. :) -> https://metalab.at/
"Metalebkuchen" is a play on words combining Metalab & Lebkuchen, which is the German word for gingerbread. I haven't yet tested the cutter on actual gingerbread dough (which I've heard is a PITA to work with), but I already made regular biscuits with them yesterday & today and they turned out great!
This is the 2nd iteration of the cutter btw. All iterations realised with the help of wizard23 http://www.thingiverse.com/wizard23. Oh, and the LED in the picture is only there for size comparison reasons. ;)
