Instructions
There are two types of hubs, a 5- and 6-way, and one type of strutcap
that will snap into the sockets on either. A completed connector must
have all of it's sockets filled with strutcaps in order to have proper
tension. Start by printing off a 6-way hub and 6 strutcaps. See if you
can snap all of the 'caps into the hub. The last one might take some
force; you can push down against a table for some leverage. You're
looking to get the tightest fit possible whilst still retaining a good
range of motion. It should be difficult to get them out once you've put
them all in. We suggest trying to adapt the hubs to fit the strutcaps,
either by scaling it using replicatorG or tuning your skeinforge
settings. If all else fails, jump into the hub.scad file and tweak the
expansion_factor variable.
The strutcaps have a hole that should accept an M3 nut. A 10mm M3
bolt should pass through the side of the connector, through the nut, and
push against the strut when tightened. The strutcap shafts are designed
to work with 3/8" / 10mm strut poles.
A 2V icosahedron requires 26 connectors (20 x 6-way, 6 x 5-way) for a
total of 176 parts. A 3V 5/9 requires 61 connectors (55 x 6-way, 6 x
5-way) for a total of 421 parts. The 6-way connectors against the bottom
of the sphere are techically 4-way connections, but you can fold up two
of the strut caps to make a flat-bottomed connector. Sure, we could
have made a separate 4-way connector, but doing so would have increased
the inventory of parts you'll need to keep track of.
