The GRAPHICA Toy Car is a 'print-in-place' .STL 3D model, designed to print in one piece. Print the car and fold down the sides and front. The wheels roll!
It's great for demos because of it's playful design and quick print time. All the GRAPHICA models are .STL files, and most print in less than an hour.
Difficulty level: 4 out of 5. Display base is included.
