The next step in the process was to design the grip. Initially, I simply pushed a handprint into the clay, but when I initially gave it to another buggy mechanic to test, it didn't fit his hand size. This made it clear that I needed a less detailed hand grip, that is less specific to one person's hand size. However, the grip still needed to conform well enough to the user's hand that they wouldn't have to wrap their hand around it to use it.

Thus, I decided to determine where the points on my hand were that I applied the most pressure when sanding. To do this, I laid a sheet of paper on top of  the grip, coated my hand in chalk dust, and pressed down on the block as if I was sanding.
