Use this as the basis for building your own poseable structures.

Basic options are: Rows/Columns - How many units to print. Ball Radius - Radius of the ball in the segment (mm). Neck Length - Distance between the ball and the socket (mm). Fluid Radius - Radius of the hollowed out section through the segment. Relief Slots - Number of slots in the socket - more slots = easier snapping together/apart. Can be removed altogether by setting to zero.

Advanced options are: Socket Tolerance - determine how tight a fit your segments are.
Socket Ring Pct - Percentage of the lower hemisphere of the socket to print, to make snapping parts together easier or harder. Careful: Too large a value and the parts will not snap together! Separation - Space in mm between printed segments. Slot Width - Width in mm of each of the relief slots in the socket.
