250ml Can Wind Powered USB Generator

This is a compact wind powered generator that can fit in a backpack. Designed for a contest for Esso fuels. A stake allows you to set it up anywhere where the ground is soft enough to poke in to it. Designed to be 3d printed simply and with minimal additional parts (and to look cool). Ideally, this will charge a power bank which can be used later to charge up various devices.

There are 7 pieces total to print, along with a few additional parts that can be purchased easily online. You may need to adjust the size of some parts by +/-1% depending on your printer for a snug fit. I also recommend small amounts of glue to make it super solid. It's possible to print without supports but the print will need some clean-up. I used very light support structure during the print mainly to help with where the large gear attaches to the body using a skateboard bearing.
