Creating new designs (Screwdriver or Salt and Pepper shakers)
08/01/18 - 12/01/18
This week we were assigned our final task which was created another useful object. This time we were assigned to design a screwdriver, however after a day or two our professor thought we should be given more options so we could do something we'd like over something he chose, so he gave us another option which was to create salt and pepper shakers. Even though we were given a second option, I still thought of going with the first option since it is very interesting and I have only seen people using it but I have went into detail and researched about a screwdriver. This option gave me the opportunity to get accurate measurements and the opportunity to learn specifically about screwdrivers. When our instructor was explained to us this task he said that the screwdrivers size varies depending on the number screw you have, which I learned for the first time. While researching I also found out the various names of different types of screwdrivers, what each component on the screwdriver is called, the way people position their hand while holding a screwdriver etc. Something I found surprising was the way people hold the screwdriver since I hold it a completely different way and the way other hold it, isn't very comfortable for me.
Then finally we started the actual design. At first I thought of creating the Philips screwdriver, however when we didn't get a tutorial on it by our instructor I decided to go with the Robertson screwdriver. Then I thought of different designs I can do for the screwdriver. After thinking of designs, I created some sketches to model my design however I haven't completed them. These are my sketches so far.
After having an idea of how I wanted my screwdriver to look like I started to model my screwdriver. First I started creating the bit. In order to create the bit part of the screwdriver, I added a sketch of a square since I am creating a Robertson screwdriver which has a square tip unlike the Philips screwdriver. The dimensions of the square were 0.13 inches by 0.13 inches. Then I extruded the square 0.16 inches. After that I added a base to square since while referencing to a Robertson screwdriver, the tip also had a base, and I created a circular base to give it more support. The circle was 0.14 inches in diameter and then I extruded it 0.15 inches. After created the base, I was thinking in style purposes and decided to create a hexagonal shank. Since I wanted to 3-D print my design to check sizes, I didn't extrude the shank a lot since their would be no point of the extra material. After the basics, I add a very minor loft to the tip of the screwdriver. This was because when looking at the tip of the screwdriver, very closely it had a very small loft on the top. To create the loft, I added a plane to the top which was 0.03 since it was a very large loft. Then, I drew a circle on the plane which was 0.038 inches. After that, I selected the loft tool and selected the square face and the circle which I drew on the plane and confirmed it which created the loft. Next, I added fillets to the loft and edges of the loft which was 0.003 inches. Then I added fillets to the square tip about 0.05 inches. After that I also added fillets to the top and bottom of the cylinder base I created. Finally, I added fillets to the edges of the top face of the hexagon which was about 0.05 inches, this was to add a unique shape to the shank. This was my design which I will be 3-D printing to test on Monday, January 15, 2018.
