I designed a vase in Tinkercad using several of the techniques I learned through the lessons on the website.  I used the workplace feature to place the stars and circles on the vase.  I used the hole feature to hollow out the inside of the vase.

In the end, I thought I had a good result for my first vase attempt.  I saved the object as an .STL file and loaded into Cura and created the .gcode file.

Into the first hour of printing, I noticed that I had a bit of a problem.  One of the holes I had put in the vase had cause the bottom of the base to become unstable.

Examining it carefully, I determine at this stage, the vase would still hold water, so I let the printer continue.

Three hours into printing the vase, the printer stopped.

There were no mechanical problems with the printer, it just though the print was finished.

Researching this problem, I found out it was not a unique problem.  It happens when the .gcode file is not completely created.  Steps to take to make sure the .gcode is created correctly are: 1) Wait until the object completely loads into the software package (Cura).  2) Do not print through the USB cable this may interfere with the printing.  3) Make sure the .gcode file is saved to the SD Card.  4)  Always eject the SD Card from computer before removing the SD Card.

I did not attempt to reprint the vase.  I need to tweak it first and other design have capture my attention.
