I am trying to print a hole in the bottom of a vase for drainage using Cura spiralize mode, any ideas?

Hi there, the title says it all. I tried using spiralize mode, I also tried printing it in regular mode with 0 top layers and 0% infill and no matter what I do it does not work or does something funky. Any thoughts? I just want drainage holes in the bottom of my vase and the geometry is too complicated for me to add a consistent wall thickness. I'm modeling in sketchup which is not the best but it's what I know.

I guess there are defects in the model. SketchUp is going to cause you endless headaches and problems: it does not close its vectors, so the models are not watertight solids, but sort of "glued together paper models". And it often has duplicate walls and other defects. It was only made for visual representations, not for 3D-printing.

 

It will probably take you far less time to find and learn another CAD-editor, than continue in SketchUp.

 

I am using DesignSpark Mechanical from RS-components, free but requires registration. However, this is only for geometric technical shapes, not for smooth organic shapes. But there are other free CAD editors. Take a look at demos and tutorials on Youtube, and find one that appeals to you.
