K'nex Dome

School's out, so I am able to begin building massive outdoor structures again. Here is the first of what I hope will be many.

This K'nex dome spans over 14 feet and is almost 6 feet high at its center. Each leg is 10 feet long, but only 3 inches thick. I designed this dome to test a modification of the k'nex arch I used in The Labyrinth. The dome was built in 10 hours by Austin Granger and Sam Ihlenfeldt and uses over 5,500 pieces.
