Are you interested in learning more about using Tinkercad to design specifically for 3D printing? Our friends at PrintLab have developed a great (free!) online course that covers 10 essential tips to achieving quality prints on FFF (Fused Filament Fabrication) 3D printers. From overhanging features and bridges to wall thicknesses and tolerances, you'll be sure to find some handy tips to help you get the best possible results from your 3D printer.
This course is great for teachers (there is a quiz at the end!) as well as anyone who wants to hone their design for 3D printing skills. Check it out!
