Hi everyone! This is my entry for the Envision the future design challenge. As suggested by Pinshape, I asked a visually impaired which problems he encounters during the day and how 3D printing could help him. He said that when he wanted to drink something, he don't always remember where on the table he exactly put his glass. Often he accidentally hit his glass causing it to fall and break or spill. My design is a possible solution for this problem. It is designed for 2 types of glasses that I have at home, but I added the original design files so that everyone can adapt it http://jmp.sh/b/8NhnTqRZQ4sLYE... . I also try to make it a customizable design. I uploaded also a small video, you can access it through the link. If you can't edit the file, send me a message with the dimensions of the glass and I will make the STL file for you. Hope it is useful for you!
