Overlapping structure when beveling (SVG) curve I hope somebody can give me some tipps although I don't really know how to phrase my problem for a suitable title.

I want to create a path in Inkscape and import it as an SVG to blender. When I create the path only two nodes can be joined, not 3 or more, so I get an overlapping path. 

When I import the path to blender, bevel it and create a mesh with it, the structure is still overlapping which causes problems when slicing the object for the 3D printer. 

Is there a way to avoid overlapping or get rid of it? I hope you know what I mean.

Thanks so much.
You can do this quite easy with help from TinyCAD add-on and some modifiers.

Steps:


After importing SVG convert it to a mesh - Alt+C > Mesh from Curve/Meta/Surf/Text.
Enable TinyCAD add-on.
In Edit Mode select two crossing edges and W > TinyCAD > VTX Auto. 


  Important! You should have only two edges. Sometimes a little clean up
  could be needed as in example below. Use X > Dissolve Vertices to do this.



Add Skin and Subdivision (use level as needed) modifiers.
In Edit Mode after selecting all vertices scale them with Ctrl+A and tweak Branch Smoothing in Skin modifier as needed.
