Doric Style Column Container

A similar container was submitted by AEzkaton, but the cap could not be screwed onto the base due to incorrectly matching threads in the base and cap.

I liked his idea, so I completely re-designed it in Autodesk Inventor.

It prints well with no supports, and has compatible thread that screw easily into the base, and a tight conical seal that shows no seam when the cap is seated.
