Heavy Duty Motor Controller

thingiverse

NOTE: You may have to set the part scale to 0.001, because I export stuff weird. This is meant to control a heavy-duty motor. A dpdt switch (non-momentary) is toggled by the servo (I hot-glue a MG996R into it) , which can then be controlled by the microcontroller of your choice. There is only forwards, backwards and neutral. It is recommended this is used for motors that either do not require precision movement (like a remotely controlled vehicle) or build in limits (like a linear actuator with end-stop switches) or to combine with other means of measuring the motor.
