servo mount RR turn-out

thingiverse

I required a platform to support a servo that would rotate my model railroad's turnouts. Fortunately, this compact Chinese servo, the SG90, proved to be an ideal fit. To secure it in place, I used 2mm screws. The thin steel wire employed is a 0.6 mm welding wire, but other materials could also be suitable. With Arduino as my control system, I can effortlessly operate the servo.
