This is the uni-knob! A universal knob, that fits onto most rotary encoders and potentiometers!
With the F3D file, you can easily customize the looks of the knob, so it fits your preferences to perfection!
Now I will show you how to customize, and make your own knob!
Bear in mind, you will need Fusion 360 to do this.
The software is free for every hobbyist and can be downloaded here: https://www.autodesk.com/products/fusion-360/personal
Open the F3D file.
Open the “modify” menu, and select “change parameters”
Now you will be able to change the different parameters of the object by changing the values in the “expression” column, and therefore make your own knob with your own parameters!
