Snap Linkage Bars, Math Models

thingiverse

Snap Linkage Sets I believe that everyone should experience the joy of building linkages before delving into abstract geometry. These structures are easy to construct and offer a wealth of opportunities for kids to explore the math behind movement and shape. With 3D design becoming more accessible, I've designed these sets with K-12 teachers and students in mind. The center-to-center distance is 40mm, providing plenty of room to experiment. There are two types of links and four types of pins, allowing for a wide range of constructions. To fix a point, use a hollow pin, and to connect three bars, use a three-layer pin. You may also need spacers to align the bars in space. The possibilities are endless. Print a batch and give them to your kids. They can even insert a pencil or pen into the handle ring and draw as they play. Just remember to educate young children not to put small parts in their mouth.
