What am I going to build for my project? 

In the grade 9 engineering project, I have decided to create a stress reliever toy that involves gravitational potential energy and kinetic energy. This stress reliever toy has a cube and a mechanical key switch. The cube will be hollow inside and can fit the automatic control. I will not be using prebuilt switches and keycaps to increase complexity and will attempt to create them myself. The first step to creating the button was to research the key controls. I looked at the Cherry MX switches and integrated some design elements to ensure that my design would be more viable using a 3D printer. After drawing all the blueprints for the key switch, I drew them all on paper and included the dimensions. It has the same layout as the Cherry MX switches but contains a difference in size. The designs drawn are here below.

Some possible materials being used are plastic filament and a metal spring. Since I will be 3d printing almost all of the components, I will need to learn how to use fusion 360.
