The file 'Bike Light Ball 3D Printer Model' is (stl) file type, size is 33.4KB.
I wanted to make a little throw ball for my nephew that blinks/lights up. So I took apart a little flashing bike light and measured out a hole in tinkercad that would hold it. I also added holes for a rubber band to keep the 2 parts together.
