The Gizmo 3D Printers software is called Gizmetor. The name comes from joining Gizmo and Creator. This is exactly what the software will allow you to do. Create Gizmo's on a DLP 3D printer. The software runs on Java 8. It uses 3D extensively so an up to date graphics card and driver will be required.
Gizmetor will become available again when a provisional patent has been lodged for the hotspot compensation. Currently there isn't any support for this app since it is still very much in development.
The library page shows all the 3D objects in your libary. You can add as many directories to the library as you want. When double clicking on an object the application will load it into memory and you will be able to turn the real 3D object around in the library tab.
