  • Etape 1

    From the blueprints/plans section, download the model and report it or print it on a thick A3 paper.

     

    Spray the other side of the paper with glue and cover it with aluminium foil with the shiny side facing out.

     

    Cut out the two shapes with a pair of cissors.

     

    Join the two ends of the larger shape to form a cone, with the shiny part inside

     

    Attach the two parts by gluing the tab.



  • Etape 2

    Report the two points on the shiny side of the disk.

     

    According to the drawing, glue the circle on the wooden board with the glossy side up.

     

    Drill through the two points with an M5 bit.


  • Etape 3

    Using hot glue fix the reflector on top of the disk.


  • Etape 4

    With a hacksaw cut two 16cm long pieces of threaded rod.

     

    Pass the 2 rods through the holes and fix them to the board with nuts placed both sides.



  • Etape 5

    Unfold 5 paper clips according to the drawing.

     

    With pliers cut off a section from the small paper clips (B).



  • Etape 6

    According to the diagram, create a support for the mobile at 4cm above the board with 2 paper clips (A type) fixed in between nuts.

     

    Close to the top of the metal rods screw two nuts against each other.

     

    Pass on each rod a washer, then a paper clip (B type) followed by a washer and tighten one side with a nut and the other with a winged nut.

     

    Finally, fix the large paper clip (C type) using a winged nut.



  • Etape 7

    Shorten the tube stopper (about 1 cm) and with a 6 mm bit drill through the stopper.

     

    Make two holes in the ping-pong ball with an awl. One on the top and the other one on the lower side.



  • Etape 8

    Cut the ends of the transparent tube in diagonal.

     

    Cut off a branch of the cross junction and slide it on the tube.

     

    Slide the tube through the candy feeding-bottle cap. Slide on the other side of the tube the stopper as shown on the drawing and finally the tube stopper (to help the different elements slide along the tube it is possible to spray some silicone.).



  • Etape 9

    Glue the strip of corrugated fiberboard on the 2 thick cardboards placed end-to-end.

     

    Fold the cardboard (the places where to fold are indicated by doted lines) and glue the 2cm flap on the back of the wood board just above the nuts.
