Aquarium Overflow Guard

thingiverse

I created this guard to fit over a 1" 90*degree PVC elbow mainly used for the overflow of reef tank water into the sump. I kept having snails clog my overflow at night so i decided to solve the problem. This guard will keep snails, fish, and large debris from clogging the overflow. Fits around the outside of the PVC overflow, but could be scaled down to fit on the inside if desired. I scaled the height a few times to get it right to fit flush with the top of the rim of the tank. Everyone's overflow height isn't the same. all edges are rounded to promote smooth water flow through guard. Print Settings Printer: Da Vinci 1.1 plus Rafts: Doesn't Matter Supports: No Resolution: 2mm Infill: 100% Notes: Print in ABS 100% Infill to keep from floating in tank. (or scale height so it hits top of tank and still covers overflow and print at 50% Infill)
