About this 3D model

After buying a new lawnmower, there was nowhere to neatly store the power cable. So, I have created a hook that fits onto the tubing of the handle for the mower. The cable can be coiled up and hung on it when the mower is stowed away. The hook is designed to fit loosely over 20mm tubing. The end of the tubing has to be detached from the mower so that the hook can slide on.
