Optional: 3D Printed Parts

There is a saying: when you have a hammer, everything looks like a nail. Well, my current hammer is a Printrbot Play and I am constantly looking for justifications why I spent (only) 400 bucks on a useless machine (my wife thinks so;-)). It so happens that I found two “nails” for 3D printing in this project: The AA battery holder and the foot mounts. The battery holder will accommodate the LiFePo4 battery, while the foot mounts became necessary since there wasn’t enough space beneath the scale for the battery. The battery holder is a wonderful parametric OpenScad project from Thingiverse: http://www.thingiverse.com/thing:456900 Since I only had a single cell I parametrized the print accordingly. The foot mounts I designed myself in OpenScad using the measurements from a digital caliper.
