New Motor casing for the Geared motor

We 3D printed a new motor casing that will house the geared motor we recently bought.

And the picture below shows us using a software to edit the infill and the supports when 3D printing the motor casing.

The mistake made

We made the casing for the motor a few mm smaller than the actual motor itself, thus we had to file the insides of the casing to make it fit the geared motor.
