The radius of the dome is 2.20. This gives us the following measurements in the calculator.
Strut A: 136cm
Strut B 120 cm
The following angles need to be cut of the struts 18 degrees for the long strut and 16 degrees for the short strut.
It is important to remember to subtract the width of the connector for the length of the strut. In our case we used two different sized metal connectors. The large one being 7cm and the smaller one 6 cm. The large struts are always connected to 6 way connector so we need to subtract 2 x 3.5 cm from the long strut resulting in a length of 129cm. The shorter strut is connected to a small connector on one side and a large connector on the other side so we need to subtract 3 + 3.5 = 6.5 cm resulting in a final length of 113.5cm for the shorter strut.
