Parts that bend or rotate, allowing for a wide range of interesting building techniques.
Hinges allow parts to bend on one axis, turntables allow parts to spin in place, joints allow parts to rotate around multiple axes, and rails allow parts to slide on a plane.
Hinges, click-hinges, and turntables allow you to connect LEGO parts at angles along a single axis.
Parts which can turn to any angle on a single axis.
Plates with one or more click-hinge connection.
Bricks with one or more click-hinge connection.
Other parts that use the click-hinge connection.
Turntables allow you to rotate parts on a horizontal plane.
The larger 'ball' and smaller 'towball' connections can be used to attach parts at any angle.
A small ball and matching socket that allows you to position parts at any angle.
A larger ball and socket that is significantly stronger than a towball Joint.
The click-socket is a very strong angular connection.
These parts are often used to add visual texture to a model by adding horizontal or vertical lines, but they can also be used to allow parts to slide horizontally or vertically.
Flexible plastic elements, cord or fabric
Plastic chain comprising individual links
While the middle of this part has the x-shaped profile of a Technic Axle, the bar connection on either end is used to attach this to other LEGO parts.
Flexible hose with ribs
Other flexible LEGO elements
Thin string and cord.
Flexible rubber bands and belts
Flexible parts with studs made from a stretchy material
