Rotation (80 parts)

Hinges, turntables, click-hinges, and click-sockets allow you to connect LEGO parts at angles along a single axis.

Many parts in the clip category can also be used to position parts at an arbitrary angle. Click-hinges are stronger but can only be positioned in 22½° increments.

Ball Joints are a separate category because they allow parts to rotate on multiple axes at the same time.
