These tiles snap together to make polyhedra of any type you wish! Regular, semi-regular, truncated, stellated, or freaky; you decide.
Customize your own with the "Open in Customizer" button or download pre-made sets of compact or light Poly-Snap tiles. The compact tiles are the blue, white, and black ones in the main picture; they are sturdy and difficult to snap together, so they make very strong models you can toss around. The light tiles are larger and shown in the red picture; these are easier to take apart and put together and print up very quickly, but the models are a little less sturdy.
Depending on your printer and the filament, temperature, elevation from sea level, day of the week, etc, you may need different tolerances for your snaps; you can modify this in the Customizer.
A few technical notes and tips are listed in the Instructions tab. Detailed walkthroughs of how we used OpenSCAD to make Poly-Snaps to construct particular models are at the links below.
