I made this wall hanging vase from a vase designed by my wife and it turned out very nice. It is hollow all the way and stands over 7 inches tall as printed here so you have plenty of room to change how it looks by simply by changing artificial or dried flowers of your choice. And you can make it larger or smaller or use the G-code for click and print for this size. It can also stand on its own on a table or shelf. I have included the g-code I used to print the vase in the photos you see here. Also I made the walls thick enough that you can make it smaller in your slicer and still be usable 3D model format: GCODE and STL
