16-Piece New-Found Expandable Pinwheel - Expanded
The angle for the 16-Piece version is another "easy to find" angle. With this and the 12-Piece Modules, close estimation of the angles for 13, 14 and 15-Piece Modules can be determined. As more modules are added, the centre hole of the model becomes larger and when expanded, becomes more like a ring than a pinwheel. I think it is also possible to reduce the size of the centre holes and I am working on it. The photos show the model in the closed and expanded form. The modules are folded from 7.5cm squares normal Kami. Many thanks to Andrey Hechuev's 8-Piece New-Found Hope Star which has inspired me to come up with this Expandable Pinwheel Series.
