This was the model we used for our published study in the Journal of Surgical Research. http://www.ncbi.nlm.nih.gov/pubmed/24721602 It was a demo of the concept that many things in and about the hospital could be printed using readily available technology, such as Reprap. I've included a copy of the PDF to download. Also, banana for scale Instructions This was printed at 75% infill, 150 micron resolution, and withstood the equivalent of nearly 30 pounds before deforming.
