I followed some of Paul McWhorter's youtube lessons for Arduinos and bought an Elegoo Kit full of sensors, motors and various other electronic goodies. You'll get parts, but no mounts or knobs. So, I made a mount and fan blade for the motor, a knob for the dial button, an arrow to mount to the stepper motor and a ping pong size ball to help with LED light diffusing which I used clear PLA for. Maybe, more to come in the future.
