What gets built

Design a simple way to organise small accessories.

What it practises
  • Planning space for your own accessories.
  • Drawing solid panels, checking clearance and assembling with broad seams.

Success criteria
  • The lid can be removed, and items cannot pass under the dividers.
  • There are three compartments with different proportions; the divider bottom joints are closed.
  • Solid panels and broad seams hold their shape during careful use.
