Our library here in Elmhurst, IL has a 3D printer, among many other cool things like large format printers, knitting machines, silhouette die cutters, video and sound equipment, and much more available to residents. So I have been working with my daughter on some projects. This is my daughter's first project, a model of a makeup case. The material is a corn bioplastic and we used the suggested beginner's program Tinkercad to design. Then just send the file to the library for printing. Easy as can be. Quite fun also. I hope to share more projects with you in the future!
