I am wondering if a wire in my model will be too fragile using the strong & flexible plastic. From the guidelines ( http://www.shapeways.com/materials/strong-flexible-design-gu idelines), it appears that the maximum cantilever (free end) wall length/thickness ratio should be at 166:1. I have a wire supported on each end that will be a length of 242mm and diameter of 1.44mm (just about at 166:1). I am ok if it is flexible, but don't want it to easily break. Any expert opinions with this material would be greatly appreciated!
