A foldable cubesat

Fold your own Binar at home or at school! Grab the template below, print it double-sided, then cut and fold to put your cubesat together.

To fold your spacecraft…

For best results, print double-sided on light cardstock (150-200GSM).

Cut on the orange lines, and fold on the blue lines – don’t forget to cut out the deployable antenna, and to leave the Binar arrow tabs attached so your cubesat slots together neatly.

(And if you want to give your paper cubesat a level up, check out our Bintroduction to Electronics project…)

Why fold a cubesat?

Binar is what we call a 1U cubesat – that means a cube, 10cm on each side. Being a standard shape means it’s easy to fit in a rack to get us our ride to space.

But being a cube also means it’s easy to fold out of paper. We’ve combined our actual design files with a standard folding paper ‘net’ to create a model you can fold yourself.

While our paper cubesats aren’t going to orbit any time soon, they would make a great addition to your bedroom or classroom.

Our real cubesat folds too.

Binar-2, 3 & 4 fold for real – they’re equipped with deployable solar panels, which double the amount of power our cubesat has available to do science.


They’re powered by a shape memory alloy, or SMA, which changes shape when we heat it up using Binar’s batteries. That lets us avoid using hinges and motors, which can be unreliable in space.
