Hello!
I have a small nano tank with a 3d printed overflow that is working perfectly!
I had flooded my room multiple times figuring this project out so this post might help stop that.
I have designed a little overflow and a zip file for it is below if you want it! Its not perfect but it works for me.
I used a Self Priming Diaphragm pump to create a vacuum in the overflow.
Amazon product
here is what I did:
1) printed the pump out and air tube connector on a 3d printer.
2) IMPORTANT!!!!! the 3d print is mostly water tight but not air tight so air will leak into the vacuum in a minute or two if you do not do this! Cover the body of the overflow with fish safe superglue and do multiple layers!!!
3) Of course air will leak in over a day or two so it is vital to attach a Self Priming Diaphragm pump to create a vacuum. So drill a hole in the top of the overflow and glue the air tube connector on top of it.
4) Attach the tubing to the overflow and the pump. (in the overflow design there is a tube in the bottom of the overflow. It works to but it is hard to connect the tubing to it)
5) IMPORTANT!!!! the pump creates tiny air bubbles (IDK why that happens but it does) so put the output of the pump in the return to the sump not the input to the overflow of the tank this will create less of a vacuum in the overflow.
Check for kinks in the tubing!!! (this applies for everything in life tho)
