Threaded Death Star Pieces Parts

I'm new to 3D printing, so I thought I would try and do some threaded pieces, worked out very well, I was surprised at how tight of tolerances my new Ender 3 Pro can produce...

I printed in Silver Silk PLA and Shiny Black Silk PLA, 210 degrees and 60 degrees, the sphere and threaded insert were drawn in Fusion 360.

Sphere is 75mm in diameter, the threads are M50 x 4, I designed .10 mm clearance in two faces of each of the threaded parts...

Parts between multiple prints interchanged...

FIrst "Thing" ever...
