For DEMto3D parameters, spacing values were tried between 0.2mm - 10mm and also scales between 1.000.000 and 100.000. Both proper runs and crashes lead to empty STL output which contains only two lines: "solid model" "endsolid model".

Hi Peter,
I understand the plugin has some limitation. I also encountered some
issues when testing it for publication.
Please refer to the plugin bugtracker:
https://github.com/jawensi/DEMto3D/issues
All the best.
