Our bookshelves sit on pins within the bookcase. Three pins have recently gone missing and our bookshelves were a mess. On their own, Aidan and Alayna thought they should make new pins in Tinkercad and print them out on the 3D printer. It worked! They measured one of the original pins, designed a new pin using the specs they gathered, and printed them up. Thanks to both students for saving our bookcase!
