(...) Further measurements show that connector #3 is 22.5 degrees - this means you can use these to make a jointed 90 degree arc with 5 panels (the ends would be perpendicular to each other). Would this meet your design requirement? (16 years ago, 2-Oct-08, to lugnet.robotics)

(...) It doesn't need to be exact, just repeatable. I need to make an armature of 4 or 5 successive 15degree "turns" to support some panels that are making sort of a jointed arc. I'll give the technic pieces a try. Almost jumped for joy at Nick (...) (16 years ago, 1-Oct-08, to lugnet.robotics)
