Round 3x3x2 Brick with Axle Hole (73111)

The LEGO® Round 3 x 3 x 2 Brick with Recessed Centre and Axle Hole (73111) combines a smooth cylindrical exterior with specialised internal connection points. Its recessed circular opening contains four connection tubes arranged around a central cross-shaped axle hole, making it a useful element for both structural and Technic-based constructions.

Measuring 3 x 3 studs across and 2 bricks high, this round LEGO® brick provides a compact cylindrical shape for custom models. The smooth outer wall is particularly useful for rounded housings, engine details, columns and mechanical assemblies, while the central axle connection allows compatible Technic axles to be incorporated into a build.
