Screw together sphere

This is a 3 part sphere I made a little while back. This sphere uses a printed thread to hold the whole sphere together. This allows you to print the sphere without support. This also helps in producing a sphere that is more symmetrical on both sides Vs printing a one part whole sphere. The diameter of the sphere is 1.5in. I printed everything without supports. Simply print the one sphere half twice. The sphere pictured above was printed in abs and acetone smoothed. I can't guarantee that this will properly screw together for everyone, as different machines may print differently than the wanhao v2 I printed this on.
