DIY Automatic Marble Shooter from Recycled Materials
Posted: Sat Jan 03, 2026 3:13 am
I’m planning a DIY project to build an automatic marble shooter using only recycled materials like plastic bottles, PVC pipes, and old springs—no electricity or compressed air. Has anyone tried something like this before? Any tips for designing a safe and reliable feeding mechanism and adjusting the shooting force so it works consistently for both small and medium marbles?
