Inside working of 3D printed PLA Beads

This technique came through researching how to create a child’s rattle sound in a large installation pieces I was creating that involved 107 of these beads being suspended from a ceiling. The interior of these PLA 3d printed beads is the Gyroid infill option in the slicer settings of your chosen slicer programme. While the Bead is printing two teaspoons of silica beads are poured into the print. It is important to not stop the print to do this and to add the beads after a high point that will admit the beads without lying in the way of the printer head. After you have added the beads let the printer finish. The result is a long and clear rattle sound when turning the bead.
