Clamping Knob For M8 Nut

thingiverse

While getting ready for a family outing the day after one of the securing knobs for the car's rooftop bike rack snapped in two. Although the knob holds a standard M8 nut I could have simply used a wrench to tighten it, but instead I decided to create a brand new one. This is a securing knob which grasps a regular M8 nut and can be attached to a M8 threaded rod. This is what makes 3D printing so exciting - being able to manufacture your own spare parts.
