Hamster running wheel with 6003 bearing(25cm)

Hamster Large Running Wheel 25 cm 🐹

This is a 3D printable large hamster running wheel designed for small pets that need more space and a smoother running experience. The wheel has a diameter of 25 cm, making it suitable for hamsters that require a larger wheel to help reduce back bending while running.↳

This model is designed to use a 6003 bearing, which provides smoother rotation, better stability, and lower noise compared with a simple printed shaft structure.↳

Bearing Used 🔩

Assembly Tips 🔧

During assembly, heat the running wheel and the wheel bracket with a hair dryer first ♨️.
This allows the printed material to expand slightly, making the interference-fit assembly easier and helping the bearing or connecting parts fit more securely.↳

After heating, press the parts together carefully and make sure the wheel rotates smoothly before use.
