Geometry Models (Free)

Here you can download geometric model developments, including regular polyhedrons, free of charge. The developers would appreciate it if you would use this material for educational purposes.


Data format

The data files are in .pdo format, which Pepakura Designer opens. Please install Pepakura Designer beforehand.
You can build a white model by checking off [Both Windows]-[Use Materials for Face] when printing.
