Cables in their own channels

Build a wide organizer with three open channels. Rounded entrances, rigid walls and contrasting colours keep cables separate so they can be lifted without squeezing their insulation.

What gets built

Separate cables on a desk without crushing them.

What it practises
  • Choosing clearance from measurements, building in layers and assembling rigid flat parts.

Success criteria
  • The approximately 120 × 60 mm base sits flat; the whole organizer is approximately 30 mm high.
  • The three channels are open at the top, have rounded entrances and clear widths of at least 8, 12 and 16 mm after cooling.
  • Each cable rests loosely and can be lifted by its insulated section without pulling the connector.
  • During insertion and removal 3 times, the organizer does not tip over and the insulation has no pressure marks.
