I have spent a few years iterating this project. Finally it is fairly simple and reliable. This rubber band gun shoots bands from a MAGAZINE. It uses small “rainbow loom” bands, which allows the design to be compact. Unlike other repeaters or gatling guns, this mag fed gun stores its ammo unstretched. This allows multiple mags to be loaded for long periods of time without the worry of bands breaking due to fatiguing rubber. While other designs change trigger pull weight or cocking force with each shot, this one stretches just one band at a time giving a consistent racking experience. There is a hollow grip for convenient band storage and an access port in the slide for monitoring, and clearing jams. Full demo and assembly video:
There is also an instructional PDF in the files page containing slicing and post processing recommendations.
