This little fidget toy demonstrates a rack and pinion gear that converts oscillating linear motion into continuous rotary motion.

Lots of fun with just around 2m of filament.

If someone wants to create additional flags/rotation indicators, the socket in the gear is 4x4mm square.

Assembly

Slide the sleeve over the outer slider with the small tab facing to the outside as shown. Place the gear in the slot as pictured.

Use the slider to push the gear under the sleeve. Lift the tab with a tool if necessary.

Insert the flag to point towards the inside when the fidget toy is closed.

Happy Printing and Fidgeting!
