I am trying to print a coaster using an EPS file. I have opened it in Inkscape and saved it as a SVG file to then used both Blender and Tinkercad to create an STL file however a number of parts appear to be just space. I have tried a few solutions to correct this through following AI ie in Inkscape using the Object to path function and ungroup but it didn't work. Any advice on how I covert the below picture to be able to 3D print without losing any of the detail.
