Ghost
The GRAPHICA Ghost is a quick-printing .STL 3D model. His tongue prints from inside the model and moves in and out using the lever on the back of the model. It's all one piece. This Ghost is the one that comes in the GRAPHICA Kit. We also offer his buddy, Mega Ghost as a bigger free model, in case you want to try out the GRAPHICA chips before buying others.
You can use the Ghost to test your 3D printer's ability to print mechanical moving parts. This model is a crowd favorite due to it's fun and mischievous design. 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: 2 out of 5. Also comes with a display base.
