DecaCircle

This model is a spherical shape built from 90 pieces.

The .3mf file should be printed twice to get all the parts needed for a sphere.

The pieces assemble in sequences of three. Nine pieces form a full circle. The joints at the end of the pieces are made to only fit in sequence.

Assembling the sphere is somewhat troublesome. I was afraid to break some pieces in the process, but it worked out. It is recommended to try and slide other joints somewhat or fully out of assembly, if another joint appears impossible to assemble.

I would expect it to be possible to make a larger sphere if the pieces are scaled up. Make sure to scale all dimensions equally, and 3x30 pieces are needed in any case. I have not tested scaling the pieces. If the pieces are printed as-is, they assemble to a sphere with a diameter of 20 cm.
