USS Enterprise 1/350 model nacelle enhancements

I recently got a Polar Lights USS Enterprise model kit, but the motors provided are too noisey. Plus, the fan fin's did not match the TV model. So the parts here are to add a DC 5V stepper motor as a quite replacement. Plus the jig to cut out the aluminium tape for the fan fin detail.
Extra parts needed:

*DC 5V 2-phase 4-wire gear stepper motor full metal Gear reduction step motor.
*L9110S H-bridge Dual DC Stepper Motor Driver Controller Board for Arduino.
* ~2mm brass so
