Replacement for frontwheels Nilfisk Multi II 30

I bought a Nilfisk Multi II 30 Inox vaccuum cleaner, where both front wheels had been shattered during transport. Both metal pins that connect the wheels to the body are intact, though. These support stilts fit the metal pins and thus replace the wheels, so the vacuum cleaner is stable and can also slide on the workshop floor. Use at your own risk, don't use if your floor must not get any scratches.
