🧊 3D LABS COURSE · CLASS 1 → 12

3D Labs, from Class 1 to Class 12

What 3D design is, every tool in the 3D Lab, how a 3D printer works, and the 3D maths of your school book. Every unit: watch a short film (take notes and save them as a PDF), answer 3 quick questions, then build it yourself in the 3D Lab.
