About this 3D model

Replacement pendulum for this kids' science toy https://softologyblog.wordpress.com/2012/04/11/chaotic-oscillating-magnetic-pendulum-simulation/ There are 2 in the file with different thicknesses, you can scale the z-axis as needed leaving x and y alone. Due to being tall and thin, there is a support wall between the objects. This needs to be removed carefully post-printing.
