this is a connector design for assembling a 2V geodesic dome structure. based off the wizardry of c60's original Dome Connector, we've improved the design by shaping the hexagonal connectors like hexagons, and the pentagonal ones like pentagons — making it much easier to visually differentiate between the two different connector types. additionally, we've added pairing notches above the 16° B-length struts on both connector shapes, to help accelerate assembly.to make a dome, you'll need 26 connectors (20 hexagons and 6 pentagons) and 65 struts (35 of length A and 30 of length B).to make a sphere, you'll need only six more pentagons (for a total of 32 connectors) and 60 each of strut lengths A and B.this design uses 10mm holes that fit 3/8" hardwood dowels quite nicely, but feel free to adjust the script to your liking. to determine your strut lengths, use a calculator:http://desertdomes.com/dome2calc.html http://simplydifferently.org/Geodesic_Dome_Notes?page=3#2V/L2and refer to this diagram for assembly:http://desertdomes.com/graphics/dome/2vdiagram.gif
