A set of gears to multiply the range of a standard servo -- a Turnigy 1501MG in this case, probably overkill -- to tilt the slats of a wooden venetian blind. Direct drive wasn't enough to get the full range of motion out of this blind.
Print one pair of gears: I've found that the 25-10 teeth combo drives the full range of the blind once I tightened up the cords inside.

A separate rig using the motor from a cordless drill and some relays to winch the blind up and down is in progress.
The servo is connected to an Espruino Pico with an ESP8266 and two power regulators (5.5V for the Servo, 3.3V for the electronics) to internet-enable the setup. A simple web app controls this, along with 433MHz power relays controlling lights, desk fan, and monitors; as well as relays to control bed head/foot motors for reclining.
