This is my fully 3D printed design for a Dual Concentric Rotary Encoder with Push Button. It's useful for making the knobs for flight-sim radio panels, where there is an outer knob to set the smaller digits, and an inner knob to set the larger digits.
It's inspired by a design I found on Youtube, where the designer, Theo Deckers, CNC'd a bracket to hold two regular rotary encoders together. I don't have access to a CNC machine or the parts that Theo uses, so I decided to design one purely us...
