# 3D Printed Aquaponics Bell Siphon This 3D printed aquaponics Bell Siphon is a device used in aquaponics systems to regulate the flow of water between the fish tank and the grow bed. The design is customizable and available in OpenSCAD format, which allows users to modify and adjust the design according to their specific needs by adjusting the available parameters. uirements. The benefit of using a 3D printed Bell Siphon in an aquaponics system is that it provides a cost-effective and customizable solution. 3D printing allows for quick prototyping and the ability to make adjustments to the design as needed. Additionally, 3D printing technology makes it possible to create complex geometries and shapes that may not be feasible using traditional manufacturing methods. Overall, this customizable Bell Siphon SCAD design provides aquaponics enthusiasts with a flexible and cost-effective solution for regulating water flow in their systems. # What is a Bell Siphon? The bell siphon is an automatic siphon used in hydroponic and aquaponic systems. It allows for the media bed to flood and drain without a timer, relying on the flow rate of the incoming water. It operates by using a vacuum created by air trapped in a bell-shaped chamber to pull water out of the grow bed and into the fish tank, creating a siphon effect. Once the water level in the grow bed reaches a certain point, the siphon breaks, and the process starts again. For additional details see section "4.3.6 Irrigating media beds" of [FAO-UN Small scale aquaponic food production](https://www.fao.org/3/i4021e/i4021e.pdf#page=83) The two-piece design of the Bell Siphon allows for easier cleaning and maintenance. The main body of the siphon is the lower piece, which is attached to a bulkhead adapter that connects to the water line coming from the fish tank. The upper piece, which contains the bell-shaped chamber, is then attached to the main body/media shroud. Overall, this type of Bell Siphon design with a bulkhead adapter is a popular choice for aquaponics enthusiasts because it is easy to use, reliable, and efficient at regulating water flow between the fish tank and grow bed. # OpenScad Version Control on Github The source code for this design can be found on [Github/seakintruth/Aquaponic-plans](https://github.com/seakintruth/Aquaponic-plans/tree/main/Bell%20Siphon%20-%203d%20Printable) Feel free to submit issues and pull request for suggestions.
