Course details
Creating replacement parts for household appliances and furniture (like a broken oven knob or draw pull) is a great use of desktop 3D printers. In this short project course, author Kacie Hultgren takes us through the four steps needed to design and ultimately print a replacement part with your 3D printer: sketching your ideas on paper, translating notes into a digital design with a CAD program, testing the print, and then revising and improving on your model. Start now and learn to create replacement parts that are almost as good as the original.
