N20 Motor to TT Motor Converter Coupling and N20 Motor Adaptor

This design will help you to replace stock motor from TT motor and replce it with N20 metal geared motor.

Only you have to find 2mm shaft(i used 3v dc motor shaft from scratch)

• assembly process is not much.just fit the coupling to n20 motor and to other end 2mm shaft. then Get the TT motor pinion gear and attach it to other end of 2mm shaft.
