An insert for using longer screw with Thule FreeRide roof top bike rack. The rack cannot hold bikes with wide frames such as e-bikes. The insert makes it possible to replace the T shaped screw with a longer M8 screw to hold a slightly wider frame (up to around 10 centimeters).
Printed with PETG and five or so perimeters for increased strength. Needs support for the screw head pocket but otherwise prints fine.
