Is There Demand for a Native 3MF Exporter in Three.js for 3D Printing?

Hi, I've been using threejs to generate meshes dynamically based on user inputs for 3D printing. While the STL format works, 3MF often delivers better results.
I noticed there isn't a built-in 3MF Exporter in threejs, so I began working on one. My question is: would this exporter benefit others? I'm considering forking the repository and submitting a PR with my implementation if there's enough community interest.
If someone is already handling this, please let me know so I don't duplicate efforts. I'd appreciate your feedback on this idea.

Three.js 3MF Exporter Contribution
Based on the available documentation, Three.js currently offers several exporters for different 3D file formats, including:
- DRACOExporter
- EXRExporter
- GLTFExporter
- OBJExporter
- PLYExporter
- STLExporter
You're correct that there isn't a 3MF exporter in the current lineup. Given that 3MF is a modern format specifically designed for 3D printing with advantages over STL (such as color support, better metadata handling, and more efficient file sizes), your contribution would likely be valuable to the Three.js community.
Many users work with Three.js for creating 3D printable content, and having a native 3MF export option would enhance the library's capabilities for 3D printing workflows.
To proceed with your contribution:
- Check the Three.js GitHub repository for any open issues or pull requests related to 3MF export to ensure you're not duplicating work
- Consider following the pattern of existing exporters for consistency
- Include documentation and examples similar to the other exporters
Your initiative to contribute this functionality is commendable and would likely benefit others working at the intersection of web-based 3D modeling and 3D printing.
