Preparing the motors

use m-seal to fit the nuts with the motor.

Preparing the Syringes

fix the nut on the piston of the syringe using m-seal.

final setup

fix the syringe and motor in these way

when the motor rotates clockwise it pushes the piston and when it rotates anticlockwise it pulls the piston
