spring powered cellphone charger

Hi there

I need this spring powered phone charger made

https://www.behance.net/gallery/1902587/Cyclus-Step

It is a hand crank dynamo phone charger

on planetary gears with a spring.

We cant make planetary gears small enough with a 3d printer in Canada.

It will need ceramic bearing on the planetary gears to make it move

with the least torque.

It only requires a hand crank dynamo phone charge on planetary gearing

attach to a mantle clock spring.

Please tell me if you can make this for us,

thank you
