Windmill v2

A simple 3D printed windmill model designed to demonstrate wind movement.  The model consists of four curved cups mounted on a central hub and can freely rotate when exposed to airflow.  Perfect as a STEM educational project, wind speed demo, or just a fun desk gadget.  Recommended settings:  Layer height: 0.2 mm  Infill: 20–30%  Material: PETG  Supports: Needed I recommend dripping a little oil into the joint between the rod and the blades for better rotation.
