The file 'Spiral Ball 3D Printer Model' is (stl) file type, size is 1.2MB.
I originally designed this ball as a replacement for the balls that came with my son's toy (Bright Starts Having A Ball Activity Table). The balls it came with roll forever and I wound up getting tired of grabbing a broom to get them out from under the sofa. Turns out both my son and dog love this ball.
I have printed the ball from 100% to 300% scale.
