Articulated Arm

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:
