Motor enclodure and Z6 gear (for fischertechnik)

A motor enclodure for fischertechnik.
Will require some external gear, a Z6 gear is provided for the 2mm axis of the motor.
I think, I had this motor from an old CD rom drive:
Diameter: 24,6mm
Height: approx 15mm
Axis: 2mm
Screw holes:15 mm apart (i.e. 15mm from inner sides)
The enclosure lid is tight enough to fit without glue.
