The GRAPHICA Skull is a quick-printing .STL 3D model designed with a moving jaw and eyes.
Use it to test your 3D printer's ability to print moving parts in one piece without bridging. If your print bridges, you can calibrate your printer before getting into a longer print, saving time and filament.
This model is great for demos because of its playful design and quick print time. All the GRAPHICA models are .STL files, and most print in less than an hour.
Difficulty level: 3 out of 5. Also comes with a display base.
