Universal joint chain that can be adjusted in stiffness and also locked.

The tapered ends (2°) allow the modules to attach firmly and also attach to tools or other grips stands  or platforms - or remix a multiple snake stand.

Can be used to keep your model in a certain position, or to hold a mirror or light, a magnet  - you know “endless possibilities” …

Examples are 8mm∅ ball and 29mm long (stringed modules 25mm per link ball⇔ball).

Add a little grease to ball and thread for smooth operation

Printing

• Supports are not needed. The Balls overhang angle should be steep enough

• Infill is not needed (a center hole adds walls where needed)

• 8mm Version uses a fine thread so print with ≤0.1 layer - There is also a coarse Version which might be easier to print

• Can be scaled up (a little) if needed stronger better use the bigger versions as scaling also increase the clearances. For the Base taper, you find a version without clearance in downloads so a scaled version is still tight. Or just use glue or a piece of paper to jam the connection.

∅12 balls can be used with the dual core:
