spring powered cellphone charger
I need this spring powered phone charger made
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,
