This is a geodesic dome connector for a pipe or pole. It's a new type of connector where it pivots around a ring between a minimum and maximum angle. This restricts the movement of the pole to the exact angles that are used in all the different types of geodesic domes, from a 1v to 8v design.

Instructions

The provided scad file has all the parameters within it to create the pentagon and hexagon connectors need to make a 1V to 8V geodesic dome.

set the outside and inside diameter of your pipe, pipe tolerance, the connector number, minimum and maximum flex angles and your good to go.

you will need one or two vitamins, that could possibly be printed.

two cotter pins per pole.
one steel ring.
both could be printed, but are not included.

your poles could be EMT conduit tubing with a hole drilled close the ends where the cotter pin goes through, if you did not have cotter pins or a drill you could use a rope to hold the poles in place by tying it from connector to connector.

I do not have a 3d printer yet so I am unable to print this. If you print it I would like to get some feedback on how it worked for you.

I have not yet figured out how to get the ring in the centre or all the connectors. I thought perhaps you could print all five connectors then when the print got half way through the ring you would stop the print and place a ring inside then continue the print. This is something I will test when I get a 3d printer, and update the files as needed.

V1.01 included nuts and bolts, in the scad file.
