I couldn't find a good enough model of the first Death Star to satisfy my needs, so I created my own. This is best printed in 3-4 parts depending if you want to hang it or have it on a desk/shelf.
For the big one I printed the sphere halves as they are oriented in the files, the lid parts separately ensure good quality for the very top of the sphere. The top part needs some supports under the rim.
Small one from the "whole" file may or may not print well, I've tried it once and it worked okay but had small issues at very top.
