Corn Sheller

This lesson describes a very cheap device developed for low-income farmers to shell their dried corn/maize crops a lot faster compared to merely using their fingers.

There are two methods to develop the device: thin-metal working or 3D-printing. This lesson describes the former. You can read-up lessons on the 3D-printing method here: This lesson will be completely based on pictures taken from, copyright D-lab and MIT. In class, we will find ways to improve or redesign the device.
