3d printed kinetic charger case

You can create a kinetic charger using your 3D printer and some elbow grease. This lets you charge your electronic gadgets right in front of you. It would also make for a fantastic gift for that special someone. Here's how it works: Check out this tutorial on kinetic electric power chargers at http://www.slideshare.net/bulgakovatanya/elveet-kinetic-electric-power-charger and watch the video explanation at https://youtu.be/LHIOgC25BWc Here are some details you'll need. Inductor: 25x5x2.5mm NdFeB Magnet - you'll need twenty pieces of these http://www.indigoinstruments.com/magnets/rare_earth/. You'll also require two Li-ion batteries, each with a capacity up to 3500mA https://goo.gl/QbeFSE. For the coils, use eight AWG28 wires (each 0.32mm thick). You'll need two springs for moving blocks and another two for securing the battery. I printed the housing using Form Futura filament, specifically their 175mm HD Glass Blinded Pearl Blue filament http://www.formfutura.com/175mm-hdglass-blinded-pearl-blue.html. However, you can use ABS or PLA with good results as well.
