These meditation beads are embossed with 36 digits of pi. A quiet way to celebrate “Pi Day” perhaps?

Pi Day is an annual celebration of the mathematical constant π (pi). Pi Day is observed on March 14 (3/14 in the month/day format) since 3, 1, and 4 are the first three significant digits of π.

The inner spheres print on top of tiny supports within the cavity of the neighbouring bead.

Once printed, a light twist of each bead frees the ball within the cavity and the chain of beads can rotate and bend.

Small spheres are difficult to print. The model shown was printed by raising the entire object 3mm off the print bed and supporting with “tree supports” in Cura. Print one of the calibration pieces provided first.

A version with flat-bottomed spheres is included if you don’t want to mess around with supports.
