Aquarium overflow splash cap and adapter

thingiverse

The cap is designed to fit on a 50mm/2" PVC T piece, enabling a 25mm overflow pipe to pass through it. To print this item, you need two pieces in one print. Don't separate them at the thick end as they will act like a hinge, which can be beneficial. Attach these clips onto a 50mm pipe and insert the 25mm pipe as needed or install each half around an existing 25mm pipe. This low-cost accessory prevents salt creep and noise while offering flexibility for various pipe combinations (thanks to sgraber for the parametric OpenSCAD file).
