This is a Geodome that I drew in the interest of testing the limitations of different 3D printers. For those of you that download and attempt to print if you could post photos of your results and the type of printers that were used if would be greatly beneficial to my Research. There will be more to come, drawings like this with more complex shapes.
You will most likely have to resize this because the actually dome is fairly large. But just scale to however large you want and then rotate to print upside down so the supports will be more easily formed.
I drew a three dimensional triangle with all three sides angled at I believe 3 degrees and then assembled these triangles together. This assembly was then rotation created a complete Geodesic Sphere of which I cut in half.
