High-Speed BB Blowgun (Modular)

High-Speed BB Blowgun (Modular)This is a fully 3D printed modular blowgun that fires 3D printed 6mm BBs. The barrel is built from press-fit sections that can be added or removed, so you can keep it short for convenience or make it longer for more power. In testing, longer setups gave noticeably better performance! How to use:To fire, drop a BB into the loading hole on the mouthpiece and blow. Covering the hole where the BBs are loaded while blowing prevents air from escaping and increases power. The mouthpiece also has two small tabs that stop BBs from being accidentally inhaled, and the end piece includes a sight guide to help line up shots. In testing, I was able to get BBs moving at over 75 km/h with ranges of 20+ meters! How to assemble:The parts fit tightly the first time, so use a firm twist-and-push when putting it together. After a few assemblies, it becomes easier to snap sections on and off. If you want to have some extra power, you can purchase some metal balls to launch! Th
