More about Cylinders

About Cylinders

Where a round brick is solid, a cylinder part is usually a shell. Two halves make a full tube, four quarters make a big round corner, and hemispheres close off a pod or a dome. Some versions have cutouts or pin holes, so you can mount details or connect them to other parts.

  • Half and quarter cylinders for curved walls
  • Hemispheres for pods, domes and cockpits
  • Tubes for pipes and thin round sections
  • Variants with cutouts or pin holes for extra connections

Finding the right part

  • Sizes follow width x depth x height in studs and bricks, so check all three.
  • Filter on colour and condition to match your model.
  • Need a small solid round shape instead? See round bricks.
  • Printed versions are in decorated cylinders.
