Barrel Overflow & Splitter – Designed by Jozsef Nagy

A functional overflow and splitter system designed for rainwater collection barrels.
This design allows excess water to be safely redirected or shared between barrels, preventing overflow while maintaining tidy pipe routing.

🔹 Designed in Fusion 360
🔹 Reliable hose connections with smart geometry
🔹 Prints cleanly on most FDM printers
🔹 Ideal for rainwater harvesting setups

Installation Notes

• Drill a 21mm hole in the barrel for fitting.
• Use a rubber washer on the outside (you can easily find one in Amazon, etc…) or apply silicone sealant before tightening to ensure a watertight seal.
• The connection for the hose is pretty strong, but if you feel, you can add silicone or just glue it in place
