Mixel Joints & Stud-Based Ball and Socket Parts

If you're building with bricks and plates instead of Technic frames, LEGO® Mixel joints are the articulation system you need. These compact 5mm ball-and-socket elements connect directly to studs and are designed for small-scale builds that require controlled movement.

Not sure which system fits your build? Start with our LEGO® ball and socket joint parts to compare articulation types.

Often used in creature builds, Minecraft-style mobs, dragons and compact robots, these stud-based joints allow smooth rotation while maintaining enough friction to hold a pose.

Key Mixel Joint Parts (14417, 14704, 14418 & 14419)

This collection includes the most searched-for 5mm articulation plates:

• Part 14417 – 1x2 plate with integrated ball
• Part 14704 – 1x2 plate with socket
• Part 14418 – 2x2 plate with ball
• Part 14419 – 2x2 plate with socket

These elements form the foundation of the Mixel-style articulation system and are fully compatible within the 5mm ball standard.

Friction Joints That Hold Their Pose

Unlike loose hinge connections, Mixel joints are friction-based. This means your dragon’s neck, robot arm or creature leg stays positioned instead of sagging under its own weight. The tight ball-and-socket fit provides both flexibility and stability.

• Poseable wings, tails and heads
• Articulated Minecraft mobs
• Small robots and custom creatures
• Compact mechanical detailing

Compatible with 5mm Towball Connectors

The Mixel joint system uses the 5mm towball standard. These sockets can connect with Technic towball pins such as Part 6628 when bridging between stud-based builds and pin-based mechanisms.
