Summary

This chunky selector-knob allows you to select one of ten settings. Interface this to a potmeter to get discrete steps for 'digital' selection.

To get the detent-action, you'll need two springs from regular ball-point pens and two 5mm bearing-balls. An M4 nut and bolt holds the assembly together. A rollerblade-bearing is also needed to hold the knob on-axis.

Also works well as a fidget-toy :)
