<h3>Disclaimer</h3><p>This was initially not intended for public release so the quality is as good as I needed to be to work. Publication was due to repair design contest. This was the first part I designed in OpenSCAD. Don't expect perfection!</p><h3>Motivation</h3><p>My Uncle, a professional cook has a machine with a broken knob that turns a 6mm axle of a switch. He used a pair of pliers to operate the switch. I designed a new on and it works ever since. The knob uses the original screw to hold it in place.</p>
