Welcome to our shop! These 3D printed mobiles are the result of a collaboration between Marco Mahler, kinetic sculptor specializing in mobiles, and Henry Segerman, assistant professor in the Department of Mathematics at Oklahoma State University. They come out of the 3D-printer completely assembled as shown in the photos and ship within one to two weeks. For more info about them, please visit www.marcomahler.com/3d-printed-mobiles.
