German software engineer Mathias Dietz works for IBM in Germany on an enormous software effort, and in the evenings, he enjoys designing and printing "useful" objects on his RepRap Prusa Mendel printer. Over the last few years, Dietz has built a suite of tools to make his printing efforts less labor intensive and more predictable, and he now offers them through his website. His GCodeInfo App, the latest of those tools, is now available free in the Google Play Store. You can read the whole story here: http://3dprint.com/45741/gcodeinfo-a...or-3d-printing
