Shark Attack!

Turn the handle and the sharks circle menacing around the boat. Duuh duh! Duuh duh!

This model uses a variant of the mesh gear essential mechanism which I will shortly be releasing as a stand alone project.

Paid subscribers to robives.com can download the model for free at the link, thanks for your support! Non-members can download the parts file for £2.50


The model comes in both coloured and non-coloured versions. Print out the one you choose onto thin card. (230gsm/67lb is ideal) Score along the dotted and dashed lines and cut out the holes before carefully cutting out the pieces.


Fold over the gears to make double thickness card and glue them down.


Once the glue is dry carefully cut them out.


Roll up the three axle tubes carefully lining up the edges with the arrows as shown.


Fit the pinion gear into the pinion tube lining it up with the grey line and gluing it into place with the tabs.

Fit the 8mm tube into the square tube lining it up between the two grey lines.


Fit the gear shaft into the large gear and thread in the 9mm axle tube so that it lines up at the bottom face of the gear.


Fold round and glue the base piece leaving the ends unglued. Fit the base spacer into position. The end of a chop stick can be handy for reaching inside the base when gluing the tabs on the spacer down.


Glue closed to complete the base.


Fold up and glue the box front and box back. Note that the long triangle tube is a right angled triangle.


Crease the score lines on the box sides in preparation for assembly.

Note the four grey alignment arrows, arrowed in the picture.


Glue the two sides to the base between the alignment arrows.


With the two sides glued into place, glue and push home the 7mm tube.


Fit the large gear over the 7mm tube. It should be free to turn smoothly.


Glue the box front to one of the box sides. Make sure you glue it to one of the edges closest to the rectangular holes in the side pieces.


Join the box front to the other box side.


Fit the axle support between the two box sides making sure that the circular hole is facing towards the front of the box.


Thread the pinion gear into place between the box front and the axle support.


Glue the box back into place.


Thread the box top down over the vertical axle tubes and glue the top into place.


Assemble the handle in three steps as shown.


Glue the handle to the pinion shaft.

Once the glue is dry turning the handle should turn the outer of the two vertical shafts. The centre vertical shaft should remain stationary.


Glue together the rotating disk and tube.


Make up the shark fins from double thickness card. Once the glue has dried carefully cut them out.


Glue the fins to the disk. The wake pattern on the disk should be behind the fin.


Fit the rotating disk to the outer vertical tube. Turn the handle and test that the disk turns properly.


Assemble the boat stand and boat stand inner.


Fit the boat stand to the inner vertical tube.


Assemble the two parts of the boat.


Fit the boat onto the boat stand, you won't need to glue it down.


Assemble the boater man from double thickness card.


Glue him into the back of the boat to complete the model.

Turn the handle to see the sharks circle menacingly round the boat!

Turn the handle on the Ski Rex and watch our prehistoric friend indulge in a bit of cross country skiing!

This model is actually a mash-up of the double crank box model and the pose-able T. Rex with added skis poles and a bit of colour! I've put all the parts into one file in both coloured and uncoloured form. If you are a member you can download the parts for free at the link. Non-members can download the parts for £2.50



Let's get started!

Print out the pages onto thin card. (230 micron / 67lb) Score along the dotted and dashed lines then cut out the holes before carefully cutting out the parts. There are six sheets in this model.


Start by making the T. Rex

Glue together the four parts that make the body.


Assemble the head upper, gluing the head inners into place (Deep red in the picture) make sure the tabs on the head inners are folded inwards as shown.


Glue together the tongue support.


Glue the tongue support into the assembled lower jaw.

Curve the tongue round and glue it to the tongue support.


The arms and legs are double thickness card. Fold them over and glue them down leaving the tabs unglued. Once the glue is dry, cut out the parts.


Fit the legs into the body. Glue one of the large disks to the leg tabs. Make sure that the leg is free to move as the glue dries.


Repeat this process with the arms. Use the small disks to secure them.


Thread the tabs from the head inner through the holes in the lower jaw and then into the body. Glue the remaining disks over the tabs making sure that the head and jaw can move.


Glue on the eyes and the feet to complete the T. Rex. Set her to one side as you start on the box.


Assemble the two short crank pieces.


Assemble the long centre crank piece.


Fold up and glue down the four push rod ends to make double thickness card. Once the glue is dry cut out the hole and then cut out the pieces.


Roll round and glue down the four pins lining up the edges with the end of the grey area.


Assemble the push rods. Glue the two push rod ends into place and thread the 'Centre' pin through them. Make sure the pin is free to turn.


Glue the long centre crank piece between the two pins. Make sure both push rods are the same way up.


Complete the crank assembly by adding the two shorter crank pieces and the two pins. Make sure everything is as square and lined up as possible.


Fold up and glue down the tabs at the side of the box-top and box-bottom to make a right angled triangle section.

Fit the box-top stiffeners into place next to the slots in the box-top.


Fold round and glue the flaps on the box end to make equilateral triangle tubes.


Glue the top of the box end to the box-top. Glue it to the end opposite the long slots.


Assemble the two slider bars and slider tubes.


Glue the two slider bars as centrally as possible in the two slots.


They should look like this from the top. The slider tubes should be free to move back and forth.


Fit the crank assembly into the box end with the tabs on the push rods facing downwards.

Glue the tabs to the slider tubes. The crease on the tabs should line up with the centre of the slider tubes.


Fit the other box end and the box base into place to close the box.


Fold in and glue down the end flaps to make triangular tubes.


Fold in and glue down the flaps at the other end of the box onto the inside walls of the box.


Assemble the handle in three steps.


Glue the handle into place to complete the box. Once the glue is dry you can check that it is working properly by turning the handle. The slider tubes should move back and forth in oppoite directions to each other.


The skis are made from three layers laminated card.

Glue the three layer of card together. Curve the ends upwards before the glue dries. Once the glue is dry they will maintain its shape.

Let the glue dry then carefully cut out the curved end of the ski and cut off any excess card.


Two skis ready to go!


The skis glue onto the tops of the slider tubes. Turn the handle so that the two slider tubes are lined up with each other in the centre of the slider bars. Glue the two skis carefully into place so that they are centred on the box top. Make sure that the skis don't get stuck onto the box top. Rock the handle back and forth a little as the glue is drying to make sure everything is moving freely. Let the glue dry completely before moving on to the next stage.


The T Rex is glued to the ski by the front of the inside toe only. This allows her to lift her ankle as she skis. With the heel roughly five millimetres from the end of the ski glue the toe down onto the ski.


The poles are glued to the underside of the ski. They must not be glued to the box top. Assemble the two poles. Glue the tab on the end of the pole to the underside of the ski next to the star. Glue the circle onto the underside of the ski so that it is centred under the pole.


Glue the dinosaur hands to the top of the poles


Let the glue dry then turn the handle to see your T. Rex ski. Ski Rex indeed!

Double crank mechanism. Turn the handle on the side of the box and the two pads on the top of the box move back and forth in opposite directions.



Make this project as a way of understanding mechanisms or as the starting point for your own character based paper automata.

Members can download the parts for free from the Add to Basket link at the top of the page. Non-members can download the parts for £2.50

Print out the parts sheets onto thin card. (230 micron / 67lb) The design has no colour in it. To make a colourful model print it out on some pre coloured card. Score along the dotted and dashes lines then carefully cut out the holes before carefully cutting out the parts.


Fold in the box top and box bottom and glue down the side flaps so that they make right angled triangles.


Glue the three box top stiffeners into place. Glue the flaps from the sides of the slots back onto the box top stiffeners.


Glue together the two slider bars and thread the two slider tubes into place. Make sure that the slider tubes are free to move back and forth along the length of the slider bars.


Glue the two slider bars to the underside of the box top so that they are exactly centred in the slots.


Make sure that the slider tubes are free to move back and forth.


Roll up and glue the various pins. Use the arrows and grey areas to make sure that the edges are glue down in the correct place.


Fold over, glue down then cut out the four crank rod ends. Glue two crank rod ends to each push rod and thread the 'Centre' pin into each one.


The completed push rods.


Fold up the long centre crank...


....and glue down the ends as shown.


Assemble the two other cranks in the same way.


Assemble the handle in the three steps.


Join the two push rods together by gluing the pins into the long crank section. Make sure that the two push rods are the same way up, tabs to the bottom.


Finish off the crank assembly by gluing on the two shorter crank pieces and gluing the pins into place.

Make sure that the push rods are free to turn on the pins as the glue dries.


Glue the ends of the push rods onto the bottom surface of the slider tubes. The crease on the tab should be roughly in the centre of the slider tube.


Fold round and glue the triangle sections on the sides of the box end.


Glue the box end to the box top. Make sure you glue it to the opposite end of the box from the two slots as shown in the picture.


Thread the crank assembly into the box end and glue down the box end sides.


Fit the other pieces of the box into place then fold them round to close the box.

Fold in the tabs and glue them to the inside wall of the box.


Fold in the two tabs at the other end of the box and glue them back to back to make a triangular tube.


Finish the model by gluing the handle into place.

Now that you have completed your double crank mechanism it is time to think about how you could add a character to the top of the box. What will you make? A cross country skier? Michael Jackson moonwalking? Two pirates swabbing the deck? It's over to you!

The Twitter Bird Box is the starting point for a future Twitter Bird project. It is interesting and fun to make on its own so I thought I would release it as a project in its own right. Turn the handle on the side of the Twitter Bird Box and the double finger cams tap repeatedly on the bellows making the integral pipe tweet.

Members can download the parts for free from the link at the top of the page. The parts are available to non-members for a small fee.

Print out the first three pages onto thin card. I used coloured card to add interest to the finished model. The last page is the net for the bellows. Print this out onto normal photocopier paper.

Score along all the dotted and dashed line and cut out the holes before carefully cutting out the parts.

You can see the Twitter Bird Box working on Instagram here.

Roll the bellows paper round into a tube and glue the edges down. Line up the edges as accurately as possible


Working from one end of the tube fold the creases. Dashed lines are hill folds, dotted lines are valley folds.


Work your way down the bellows tube one row at a time.


The completed bellows


Glue up the pipe tube as shown.


Assemble the pipe end and glue it to the end of the pipe. The bottom edges should be aligned accurately with the bottome edge of the pipe.


Fold over the double hexagon piece and glue it down to make double thickness card. Cut out the marked hole with a sharp knife then cut out the hexagon.

Glue the pipe to the hexagon so that the hole lines up with the air inlet in the bottom of the pipe.
