Spherical Six-Sided Die

This is a spherical six-sided die. The center is hollow and shaped with an octahedron so an 8mm steel ball bearing (or round lead sinker) will rest in the bottom point to cause the rolled number to show on top. The way I sliced it uses just 2.72m of filament, so it is a great way to use your short leftover pieces. The .3mf file has an M600 command at layer-100 to pause the print to accept a weight, then continue. I suggest an 8mm stainless steel ball bearing, but a round lead fishing sinker would work well, too.
