For this project I had to redesign an existing screwdriver by improving it and focusing on the ergonomics of it. After designing it I had to link the colours to a specific brands that they suit. 

Here I have done a engineering sketch of an existing screwdriver as well as some rough ideation sketch's and a rough engineering sketch of an improved design of a screwdriver. 

This is a final engineering sketch of my improved screwdriver design.

Here are some screen shots of my screwdriver CAD parts done on Solidworks.

These are draft drawings from my improved screwdriver. There is a General Assembly, Exploded view, a detail view of the handle and a detail view of the shank.
