Inspired by We the Builders ( and NEOARCHAIC's N-Sphere (


One piece of a six part ball was created in Fusion 360, and Ultimaker Pioneers were challenged to modify the STL—sculpt it, add to it, personalize it in some way, embed a circuit inside, really anything is okay.

The STL file, the Fusion 360 file, and a spool 3mm filament were sent to Pioneers interested in participating in the project. After personalizing the STL file, printing it, and sending it to Ultimaker in New York, magnets, the mechanism used to connect the pieces together, will be inserted and Ultimaker NA will bring the pieces to events to share with others .

Each participant is documenting their process, and that information will be shared on the Ultimaker web site.

Materials and methods
