Modifying DG01D-E-sparkfun motor

Hello,

I am using these motors with the XRP platform. My competition rules are very loose to promote unique ideas and mine is to create a gear locker to lock the two shaft gears together to cut my reduction ratio in half. Im looking for help getting the dimensions of the gears inside the motor so I can 3d print a reliable and suitable piece for my project. Any help is greatly appreciated.

You’d need to disassemble the unit via the screws


and check 'em out

But I’d sooner just couple them and have its output paired with a single external reduction gear…3D printed internal gears are probably going to struggle (they are metal)
