Blender is not a professional CAD software, but "good for making nice pictures" is understating its abilities; as a hobbyist I've modeled a dozen or so objects for 3D printing and they slice/print just fine. There are even plugins to analyze models in Blender, and plugins for CURA to open blender files. https://daler.github.io/blender-for-3d-printing/printing/mesh-problems.html https://daler.github.io/blender-for-3d-printing/printing/mes... https://thopiekar.eu/cura/cad/blender/ https://thopiekar.eu/cura/cad/blender/
