When I was a kid one of the coolest rayguns was wielded by the Lego classic spacemen. I've had a Lego space helmet for a while so I decided I needed a full-size sidearm to match. This was designed in Fusion360, scaled perfectly from the tiny raygun I've had since I was 8. Pieces were 3D printed, finished and painted. For the removable translucent green emitter, the piece was molded in silicon then cast in translucent green resin. Internal electronics lights up the emitter with a trigger button.
