Dive into the fascinating world of mathematical toys with this 3D printed tri-hexaflexagon. Unlike its traditional paper counterpart, this model offers a durable and tactile experience, bringing to life the intriguing concept of a shape with three distinct faces. Its ingenious design allows for a mesmerizing flexing action, revealing hidden surfaces in a way that's sure to captivate. Perfect for enthusiasts of mathematics, geometry, or simply those in search of a unique pocketable toy, this hexaflexagon packs a world of discovery into a compact, 8 cm diameter form.
Make this hexaflexagon truly yours by choosing any three colors to print. While we recommend steering clear of light colors to avoid bleed-through, choosing a lighter hue for the first slot creates a symmetrical effect upon folding. Experiment with different color combinations to personalize your hexaflexagon or match it to your style.
The example photos were all printed in Bambu Matte PLA filament. Here are some of the colors that don't bleed through to the other side:
And here are some examples of colors that do bleed through.
The included print profile is designed with ease of printing in mind, but if you choose not to use it, this model requires:
Although there are only four color changes for the whole print, I haven't discovered a easy way for non-AMS owners to manually swap the filaments because the changes occur mid-layer.
Zigzag Pattern Formation: The color change lines will be your guide. Carefully fold the printed strip along the color-separating lines to create a series of equilateral triangles in a zigzag pattern.
Ensure the same colors are on the inside of each fold to maintain the integrity of the design.
Do not fold where the inside part of the fold displays two different colors on each side.
Folding in the wrong direction can significantly weaken the plastic, risking fold failure.
Pro Tip: For precise folds, use a straight edge, such as a sharp countertop to guide your folding.
The real magic begins when you start to flex your hexaflexagon. Gently pinch and push three adjacent triangles towards the center to unveil the hidden faces. Each flex invites you to explore further, revealing new patterns and colors. It's a delightful puzzle that encourages curiosity and offers endless fascination.
