On day 4, with Mr. Stevenson’s help, we finally got the printer to work! On day 4, we printed out our first face shield prototype, the Prusa RC3. It took 3 hours to print, and we needed to assemble it and tie knots at the end of it. So on day 5, we moved onto our 2nd prototype, the Manta Ray v6. We printed many of them, and overnight we printed them in a stack. There was a flaw with this design though. We could not separate them quickly and carefully, so on day 6 we were going to try to find a more efficient design.
