My device is a spoon that can rotate 360 degrees so that the food inside will not be spilled. This helps people with Parkinson's disease and people with other disorders that cause them to have shaky hands, which leads to a difficulty in feeding themselves. The Gyrospoon helps alleviate that difficulty by using gyroscopic technology to keep the spoon part facing upward at all times.
I used ABS for the parts but you could probably use PLA instead. I think that it would work just as well. I also would've used ABS and the Makerbot HIPS dissolvable filament but with such a short time frame after I had come up with my idea, I was not able to get my hands on the D-Limonene that is needed to dissolve the filament in time. You could use any printer to print out the design, but I used a combination of the Makerbot Replicator 2 and 2x as that was the most convenient for me at school.
The picture of the prototype that I have on this page is a little bit messed up. The inner part of the Gyrospoon was scaled down too much in the Makerbot software, so it doesn't fit as well as it did in the computer model. To fix this, I just added a short piece of paperclip to bridge the gap. Be cautious if using the Makerbot Desktop software to make sure that all of your pieces are scaled the same.
When I was designing my entry for this competition, I was thinking about things that help people with disorders, and I thought about spoons that use gyroscope technology. The only problem with them is that they need electricity and are made out of things other than 3D printed material. I thought that I could design a spoon that uses the same concept, but is able to be fully 3D printed. It took me a little while to first come up with a solid design that I felt could work, but after 3D printing a few pieces I realized that I had to make some changes with spacing and supports, as the first print had no supports or spacing so the handle and switch were one big piece instead of two pieces with supports separating them. After that, everything else was pretty fine except I changed the thickness of all of the pieces from one quarter of an inch to three quarters.
The Gyrospoon files come with the handle and switch together in an assembly. The switch has enough space inside the handle so that there are supports there and not solid plastic. The files also come with the outer ring of the whole thing, and the spoon piece itself. These pieces are all needed in order for the gyrospoon to function. There are some optional pieces that you can use to improve the function of the Gyrospoon even though it already functions very well. These pieces are the locks. They go on the outside of the outer ring and spoon posts (the little pins that go into the whole of the piece to the outside) The switch may also be optional. Even though it is a part of one of the necessary pieces, you only need it when you are trying to eat something that is semi-solid. You would not need the witch if you were trying to eat something like soup.
The video below is just a demonstration of how the Gyrospoon works.
