What gets built

Make a personal small item while practicing an even line and a repeating pattern.

What it practises
  • Drawing a continuous, low line.
  • Joining adjacent PLA paths on the mat.
  • Repeating a simple spacing arrangement.
  • Testing the function of a self-made object.

Success criteria
  • The bookmark has a 12 × 3 cm outline, two connected frame lines, and exactly three bands of three crossbars.
  • It is one flat piece, with no loose ends or sharp blobs.
  • Insertion and removal proceed without catching or forcing movement.
  • The book closes gently without noticeable local spreading; after the test, the pages show no signs of catching or creasing.
  • The selected rhythm can be recognized in each band; small differences support self-reflection and are not formally assessed.
