Still a work in progress (beta_v4) Purpose: Students are going to be using these with broken arrow shafts to create "One Cubic Foot" cubes to study a variety of environments. Inspired by the book and National Geographic's coverage of David Liittschwager's work: here: http://ngm.nationalgeographic.com/2010/02/cubic-foot/liittschwager-photography#/video/ Ross School Innovation Lab: http://www.ross.org/innovationlab The Book: https://www.amazon.com/dp/0226481239?tag=rosschheldes-20&camp=0&creative=0&linkCode=as4&creativeASIN=0226481239&adid=0PEY6AQ2SWG935QF3JC7&Recommended print settings for a MakerBot 2X using ABS are for 5% fill, 2 Shells, 0.2 Layer. I have have had a couple break at the 5% fill and have made some at 50% for sturdier corners, but somewhere in between is probably optimal. FYI: The helper disk that is included in the model is 0.2mm thick to help with plate adhesion.
