Geodesic Dome Concepts

2V/L2 Icosahedral Dome Concept

The plans for this dome can be found here. The concept was built using toothpicks and a hot glue gun. The length of each strut was normalized to the length of one toothpick, meaning that the longest strut was a toothpick in length, the second longest was a certain percentage of that, et cetera.

From the website mentioned above, the following parameters for the dome were found:

1The variance is the percent difference between the longest and shortest struts. The lower the value, the better.

Using the provided dome calculator at the website mentioned above, the following strut lengths were obtained. It should be noted that the strut lengths were normalized such that the longest strut is a toothpick in length.

Comments

Some things learned from building this dome concept:

A rough estimate of manufacturing time to construct this dome concept would be between 80 and 105 minutes based on the estimates listed below.

3V Octahedral Dome Concept

The plans for this dome can be found here. The concept was built using toothpicks and a hot glue gun. The length of each strut was normalized to the length of one toothpick, meaning that the longest strut was a toothpick in length, the second longest was a certain percentage of that, et cetera.
