For this homework assignment, I used IronCad to create what was first going to be a ball-and-socket joint. I decided to instead make more of a joystick because of the size constraints of 2” x 2”. Making this part actually used a bit of math to get the spacing correct between the inner ball and the outer ball/shell. To create the joystick I started with a sphere, cylinder, and a torus. Then I hollowed out the two spheres and made two holes for the support material to leave. Then the ironcad file was converted into an .stl file so it would be compatible with 3-d printing. I used the Object260 for this part for a few reasons. First, it was available and I was pressed for time. Secondly my part was very small and it has pretty good resolution and it was also small enough to be below the minimum cost of $5.00 for the materials to use the other printers (I was told by one of the lab techs).
