Overflow Box

thingiverse

The original by MrLunk was tailored for a tank with no plastic rim, whereas mine features a black plastic rim around the top, necessitating a redesign to accommodate that gap. I have successfully printed and tested it, and so far, it appears to function as intended; however, I have not conducted long-term testing yet, so I cannot provide any assurance that it will maintain its siphon during a power outage. The approximate flow rate is approximately 30 gallons per hour.
