    - Print out all parts.

    - Mount the handle with 3 x (3 x 20)mm screws and 3 nuts.
       The foremost hole remains empty (yet).

    - Bead the "clamps" and "brackets" on the (3 x 60)mm screw
       and the foremost hole.
       Install washers on both sides of each "clamp" (see image).

    - Add 2 nuts on each side of the screw (counternut)
       or use locking nuts (I used 2 red plastic gears).

    - Insert the (3 x 65)mm bolt through the rearmost holes of the "clamps".
       Let 5mm jut out on each side (for rubber band). Fix bolt with glue.

    - Use a soldering iron or a side cutter to cut a triangle shaped<br>
       flute into the upper part of the syringes piston (see image).

    - Apply some drops of oil to the rubber seal of the syringe.

    - Attach the front and rear "brackets" and mount the springs.

    - Fix the rubber band that pulls down the "clamps".

    - Clip the barrel (bird perch) onto the syringe.
