  1. Take apart the ball point pen
  2. Get the ink cartridge and cut it to length (Mine didn't fit but I hade a precut one that did so dont worry about that)
  3. The cut piece should fit on the motor if it is too lose add a small piece of tape around the motor shaft and it should fit. (Images 4-5)
  4. Then add the technic pin-axle, if it doesn't fit add some tape till its snug

Connect the Motor to the Base

You will need the motor and the base as well as the rubber band

  1. First take the motor and place it on the base
  2. Next get the rubber band and double it up on itself and and attach it to the base and over the motor then put it back on the pin
