Spaceship docking station

This is a model of a spaceship docking station that I designed in Tinkercad. It is printed in three separate pieces two of which need to be joined together while the third part, the ring, will be able to spin freely around the main part.

A brim is recommended on the large upright part so that it does not fall over during printing.

Some sanding might be required to get the parts to fit together properly.
