Oscillating Fan using SG90 servo and 40mm fan + Arduino
thingiverse
I needed to create an oscillating fan that I could control using an Arduino board. To accomplish this, I combined two Thingiverse projects: clough42's cooling fan (http://www.thingiverse.com/thing:351280) and DEF's extra degree of freedom design (http://www.thingiverse.com/thing:68876). This enabled me to mount a 40mm fan on the rotating part of the servo fixture. Next, I secured it at the bottom of a planter with screws and wired everything up, resulting in healthier-looking plants. Instructions I printed my design at .35 layer height using ABS material.
