We present the design and prototype construction of a small set of snap-together parts that permit constructing sculpture maquettes in the form of prismatic extrusions along certain modular space curves. This allows the formation of open-ended structures such as “Interaction2” by Henk van Putten and the “Coriolis” series by Bruce Beasley, or closed-loop sweeps like van Putten's “Borsalino” or Paul Bloch's “Symmetrical Enigma” and simple knot shapes. The parts are designed so that they can be readily fabricated on inexpensive rapid-prototyping machines and so that they mesh with the LEGO® DUPLO parts.
