Tetrahedron Bird : Download and Make!


Categories: , ,


The simplest of the Platonic solids is the tetrahedron, four equilateral triangles arranged as a triangle based pyramid. The pointed corners of the tetrahedron look just like the beak of a bird so here, as the second in the series of Platonic Friends I am pleased to present the Tetrahedron Bird.

Members can download the parts for free at the link – non-members can join in the fun for £2/$3

The file comes with a coloured and non-coloured version of the parts. Print out which ever you choose onto a single sheet of thin card (230gsm / 67lb) Score the dashed lines then carefully cut out the parts

The feet and tail are made from double thickness card. Fold over the pieces and glue them down. Set them aside for the glue to dry.

The legs are given the extra strength needed to hold the weight of the body by laminating them. Gently curve the leg into shape as shown. Glue the foot to the leg back.

Curve the leg-back up to meet the leg and glue them together.

Curve the leg back up at the knee to meet the rest of the leg. Glue the them together. Repeat the process with the second leg and set them aside to dry.

Cut out the tail.

Cut out the legs and feet.

Glue the feet to the legs.

Assemble the body.

Glue on the beak.

Make the eyes from double thickness card.

Glue the eyes to the body with a small dot of glue. They sit over the bridge of the beak like a pair of specs.

Glue the wings to the glue areas.

Glue the legs to the back of the body to complete the model.

Try making one of the birds from coloured card. Make yourself a flock!

  • Excellent model.

    Excellent model.

    I used to work for a company that designed the “soundfield” microphone that as two stereo pairs of capsules in a dual tetrahedron configuration. The maths for the signal processing was way beyond me, but the shape looks good.

    • Nice! Now we just need to fit

      Nice! Now we just need to fit one of those inside the bird for an unobtrusive surround sound spy bird 🙂
