this is a prototype connector design for assembling geodesic domes and spheres. rather than using preset strut angles, it uses a flexible ball joint strut connection that allows the structure to adapt to a variety of configurations. therefore, all that's required to build a dome of any scale or frequency is the proper strut length calculations, available from: http://simplydifferently.org or http://desertdomes.com

the design is based off of william adams' yazzo disc joint openscad script, modified to include a shape language of hexagons and pentagons for the six- and five-way connector types. the strut caps used in this prototype should fit 3/8" diameter dowels (but they might not)

update 3/16 — added strutcap.scad. other code forthcoming.

depending on your application, print out the proper number of hexagonal and pentagonal connectors. for each strut required, you'll need two strut caps that will attach to either end of the dowel. then, simply snap the ball-end of the strut cap into the receptacles on the connector to build your desired space frame.
