Stand for spherical models

This stand was originally requested by David Askew, thanks to him for the feedback and photos. I made up a very simple stand for any 16cm diameter sphere. Since it can be useful for many of my astronomical models, I decided to publish it in several sizes: 5cm, 8cm, 12cm, 16cm and 20cm. They can be use with other similar sizes of course, or they can be scaled to do so, as well.
The Death Star of the photo is one of my most popular models, available here: www.thingiverse.com/thing:3432933

I spend part of my time making these models, letting them available and free for everyone. If you want to support my work, you can contribute with me here:
