This is from a course called Design Methodology which is about using feedback from user testing to make a product better. In this case, the product was a screwdriver.
Two of the test models in 3D.
We started out making 5 screwdriver test models that the whole user test will be based on.
This was the one that was chosen as favorite by the users in the test.
More test models based on the favored model in the user test and comments.
More 3D modeling was done and now it started to take shape.
The next step was to figure out what color it should have.
This was the final 3D model, and it was printed in the school's 3D printer.
The final result.
