one of the gears inside of the helicopter broke
bough this for my nephew, but he was never able to use it.
the helicopter has 2 gears that are exactly the same, one of them broke and doesnt let the helicopter work correctly. i was thinking i could 3d print a new one, but i dont have the expertise to make a 3d model of the one that works correctly, i do have the size and pictures/scans of the small gear, is anyone here able to help me make a 3d model of this gear so i can print it? or otherwise know of a way i can replicate a very small gear if i have a working one?
edit: this is the gear that is working fine:
it measures 6.5mm, the bigger wheel,
the smaller one is, 3mm
and the axis hole is 1mm aprox
Esta é uma boa pergunta?
