Part 4: 3D Printing

For my first 3D print, I designed a sharp star shape at the base, which I lofted into a circle that transitions into a larger star at the top. I then added a sphere and using Boolean difference it created a crater within the top of the star-shaped structure. Initially, it didn’t match my original vision, but after revisiting the design, I found it more interesting than expected. It also turned out to be functional, as it can hold the dodecahedron we printed earlier.

The printing process went smoothly. Surprisingly, the nozzle grinding issue that occurred during my first print resolved itself this time. However, since this print took around four hours, I kept an eye on it the entire time, worried that the issue might return.
