Hand-Crank Turbo Snail–3D Printed Mini Dust Blower

Meet the Hand-Crank Turbo Snail! 🐌💨
A fully functional 3D printed mini turbine that works on 4 gears and pure human power. It doesn’t blow like a jet engine, but it’s perfect for brushing dust off your keyboard, cooling your nerves after a failed print, or just spinning gears for fun!

Each gear is numbered to make assembly simple — no confusion, no gear drama.

Just follow these steps:

Install the small gear onto the shaft, then thread it through the housing and attach the fan.

Insert gear 3, then 2, then 4 — gear #3 sits on the bottom.

Attach the handle to gear 4 through the case.

Glue the body, fan guard, and handle using super glue for a solid build.

That’s it — you’re ready to generate wind the old-school way 💪🌀
