A simple printed plug that spins with water flow, catching hair before it clogs the drain.

Goal
Easy cleaning without removing the drain grid

Description

The idea wasn't based on any physics research. It was just "try/fail". The drain grid has a central bolt that acts as the axis of rotation. Its convex shape makes the plug spin when water flows through it. The water flow spins the plug, gathering hair into a single clump that is easy to pick up.

Future improvements

There were some complains about the handle being to small. Try a taller handle for better grip
Experiment with different sizes of holes
