Geometric art of Morton C. Bradley, Jr.: https://joelcooper.wordpress.com/2012/06/21/geometric-art-of-morton-c-bradley-jr/
There's more at https://harvardmagazine.com/2012/11/absolutely-beautiful and https://www.georgehart.com/rp/MortonBradley/Morton-Bradley.html but the Harvard piece doesn't have enough images and Hart's 3d prints lack color. As Joel Cooper writes in the linked post, "I was fascinated first by the complex yet harmonious geometry of these forms, but it is really the use of color that makes these sculptures so transcendent. These sculptures are really exercises in color theory in three dimensions."
