Double Spinning Linkage Bars, Geometric Construction, Pendulum

An interesting set of three types of linkage bars with double spinning structures—spinning connectors plus grooved joints. By mixing and matching the bars, one can build all sorts of mathematical, physical, or even chemical models. They are flexible, growing in 3D and spinning in many ways. These structures are quite chaotic as you will find!

Each joint is about 35mm in diameter and is 8mm in width. They are pretty sturdy. To connect, just gently snap them together. Because of the double rotational design, it might be hard to separate them once snapped together. Please use a flat-blade screw driver to pry them open slowly.

There are three types— two connectors, one connector, and no connector. A cap is also included. They come in lengths (center to center) of 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, and 100mm.

Please use a resolution less than 0.15mm and an infill greater than 10% for strength.

Have fun and help kids do some math. Thank you for visiting!
