Cardboard Limbs

Cut a rectangle of cardboard approximately 2"x3" and fold into thirds. The leg segments you may want to size slightly larger.

Glue small squares of cardboard to the ends of the folded rectangle.

Make 8 of these segments (2 for each arm and 2 for each leg).

Link Segments

Use something sharp to poke a hole in the end of each segment.

Insert a paperclip into this hole in the cardboard.

Push paper clips most of the way in and use dabs of hot glue to hold paper clips in place. 

Allow a few minutes to cool before moving the linked segments around.

Torso

Cut a larger rectangle of cardboard and fold two flaps along slightly angled lines. 

Glue cardboard strips along the top and bottom to hold the folded flaps in place. 

Connect the arm linkages to the torso using the same paperclip technique as before.

Legs

As with the arms, build two leg linkages, connecting each with paper clips and gluing the paper clips in place with hot glue.

Hands and Feet

Connect the legs to the torso using paper clips.

Glue some cardboard hands and feet onto the model.

The Head

Make a head out of a folded strip of cardboard.

Insert a paper clip into the bottom of the head and top of the torso to link them together.

A small hole poked in the top of the head will allow for a string to be threaded through which will be used to support the marionette.

Add Strings

Use thin wire or string to connect limbs to servo extensions
