The CAD software Blender may look like the cockpit of a spaceship, but a new free course aims to prove you don’t need a pilot’s license to make cool, 3D printable stuff. 3D Printing with Blender, taught by Blender veteran Hjalti Hjalmarsson, walks beginners through the full process: designing, modeling, troubleshooting, and fixing objects destined for your printer. It’s entry-level, it’s practical, it demystifies the scary buttons, and best of all it’s free… just like Blender itself.
