I used the Shapiro Library 3d printer to make some test parts for my ENGR100 project. These tests were pieces to hold a rotary servo motor, and rotate a gear to move a plastic arm in a straight line. I needed this to plug holes on an ocarina, which is similar to a flute, in that you plug holes to change pitch. So, this print would allow me to push rubber end caps to close holes and play songs. This print revealed multiple flaws in the design, and I was able to properly make adjustments and print a successful piece. The design lab was pretty accommodating, they let me start earlier than my reservation. As well, they helped choose settings and layout for the print, and since my print was too long to pick up later, I was able to come by the next day to pick it up. It was nicely bagged, and had a good print overall.
