This project contains a SCAD file defining a 3D model of a ball-stand, useful for displaying the clear acrylic balls often used for contact juggling. The model consists of 3 rings connected together to form an equilateral triangle. Each ring has a concave indentation on top, shaped to exactly fit a sphere of a certain diameter. The rings are spaced so that when spheres of the correct size are placed into them, they touch to form a triangle.
The stl_files folder contains pre-rendered STL files suitable for 3D printing, for a range of common diameters:
