Id’ like to show you my personal 3D printing project called @GuerillaBeam .
It’s a 3D printable projector, that can use arbitrary camera manual focus lenses and LED lights. It’s solid state and portable and yet superior to classic slide- and gobo projectors.
It includes more than 700 hours of work (not counting the printing), much love to detail, and has a whole system of many adapters and tripod + accessory mounts for attaching anything you’d like (cameras for instance).
I plan on manufacturing them, and also to make them available for downloading for a small fee (CC licensed). Please let me know if you are interested or have any ideas and questions about it! Thanks
