Hello! Can you please share your export settings?

Please feel free to share the Shapr3D design and the exported 3MF file, we’ll check it soon. Anyway, if we are speaking about millimeters, 0.0165 mm is way below the resolution of an FDM printer but that does not mean we won’t find the possible causes 🚀
