9 sticks of TNT with TNT labelled straps and a small fuse on top. Inspired by http://www.thingiverse.com/thing:100740 - but i found i needed more support for my printer to do the overhanging parts and letters - so i rebuilt this from scratch using 123D Design. I printed one of these at 80% size (that's the attached image) on a Lulzbot TAZ4 with JET PLA 2.75mm orange.
