Circular to Waterfall Flow Converter

This 3D printable adapter is designed to convert the outflow from a circular outlet (like that of a pond filter or tub) into a smooth, wide waterfall-like sheet. Perfect for DIY pond projects, filtration systems, or any setup where you want to transition from a pipe or drum outlet to an aesthetic and functional water sheet.

The cylindrical base fits snugly into or over a circular hole, while the smoothly curved chute guides the water into a natural waterfall form. This helps enhance both water aeration and visual appeal in garden ponds or aquaponics systems.
