Summary Source file from this ESA page: http://blogs.esa.int/rosetta/2014/10/03/measuring-comet-67pc-g/ Inspired by the amazing work by ESA, the Rosetta and Philae spacecraft and probe, and all the people who've worked on them, I wanted to make an easy to print model of comet 67P/C-G. This uses the model from ESA, the OpenSCAD Joint Connectors from MakerBlock, and a short OpenSCAD script. Instructions Print top, bottom, and 4 pins. Trim away any excess from the pin holes (helps the pins fit easier). Put the pins in the holes on the top or bottom, and press the other half on! Should stay together with no glue.
