This is a case or holder for the Globe Demonstrator. A cool gadget by CDA GmbH using light interference to create images of star field, turning globes, the moon and their logo. You can find a demonstration at youtube.com/shorts/5QUqxmqBOQI.
Disclaimer: I’m not associated with CDA in any way nor do I own the right for the plate itself. I only made the case around it.
