28BYJ-48 Stepper Motor Angle Indicator

Whipped up these angle indicators to attach to the common 28BYJ-48 stepper motors that I was controlling with an Arduino board. Print out the PDF, cut-out and attach the protractor circle to the motor, and then pop on the indicator arm.

Some people just tape a toothpick to the motor shaft, but this is a nicer solution IMO.
