The 3D models are made specifically for use in his own 3D plugin for after effects called Element 2 [V2.2]. They ARE NOT specifically made to be 3D printed but you may try to 3D print them but your results might vary in success if you try to do so. It was suggested by a redditor that instead of trying to 3D print the model, edit and reconfigure the model files in the download in order for the models to have a high probability of being successfully fully printed when you try to do so. Here are are the 3D Models Kramer is giving for free : Remember these can only be rendered with Kramer’s specialised 3D plugin for after effects called Element 2 [V2.2] Those who dont know Kramer, he is host of over 100 tutorials and creator of title sequences for TV’s Fringe and the film Star Trek.
