Cuisenaire Rods Anti-Suffocation and Injury

We all know that Cuisenaire Rods are exceptional tools for teaching mathematics to children.

Living in an area where traditional Cuisenaire Rods have been removed due to incidents of children not being able to breathe and injuries caused by sharp edges, I decided to use 3D printing technology to offer a solution and make a positive impact on the community.

These new Cuisenaire Rods feature rounded edges and a central hole, specifically designed to eliminate the risks of suffocation and injury. Each rod keeps the traditional color coding and length to help teach basic mathematical concepts such as addition and subtraction.

The project is open source, allowing anyone to download, print, and use these tools without commercial purposes. My goal is to reintroduce these valuable educational tools in schools while ensuring the utmost safety for children.
