Arduino Battery Clip

thingiverse

Attach this accessory to your Arduino by screwing it onto the bottom part and secure a 9V battery. This device is ideal for powering self-sufficient projects. It is compatible with UNO, UNO SMD, Duemilanove, Diecimila, NG, most "full-size" clones, MEGA, and MEGA 2560. However, you might need to enlarge the screw holes if they do not match the size of your Arduino (1/8"). The Post-UNO model is for Arduinos with a screw hole next to the power jack while the Pre-UNO model is designed for those without it. Once done, drill out the screw holes and you're ready to use. You can also modify the scad file to customize the design further; the method names and parameters are clearly defined. Although, the thickness and width parameters might not be completely implemented yet.
