Indroduction
This is a 3D-printable fan that uses a rack and pinion mechanism. By pushing the rack into the gear, the gear turns and drives the fan. A rubber band return system allows the rack to slide back freely without stopping or slowing the fan. This enables repeated squeezing to gradually increase the fan’s speed. The fan continues to spin regardless of when the rack is stopped or reversed.
The Fan attaches through a thread on the axle this allowes to easily switch or remove the Fan from the handle. if you want to get creative with the fans blades I leave a step file with the bare fan hub in the files section to remix.
This is a gif of the working principle:
