Part of it might be that you are using inaccurate terminology in your searches. In Vacuum Forming a "Buck" is the positive sculpt, or mold, that the plastic is pulled over. Negative Molds are more for Resin and Fiberglass casting where something is poured or pushed into the mold to take the shape.
3D Printing the Vacuum Form buck has become pretty common and there are several threads and tutorials for it here on the site if you use the "Buck" terminology:
Hey armorsmiths! So im a bit stuck, and wondering what exactly you guys do to create vacuum form bucks? Theres a few threads along similar lines here, as well as some links from searching the net, but im struggling to find the process im looking for. So i'm attempting to make a buck for an...

(Wanted to give something back to this community and create a tutorial on how I was able to create a visor buck which can be vacummed formed. This took a load off trial and error but this is the easiest I have found to do but anyone else who has found an easier way is more then welcome to add to...

Hey folks, Im currently working on my first ODST helmet and am almost done but have hit a snag with the visor. I want to try vacuum forming I already built a little home set up and tried it with some more easily formed plastics but now its time for the real deal. What Plastic/material is...

That said, while you will find files for ODST Visor Bucks, and just the visor section that you can modify into a buck, they are not going to work perfectly with Sean's helmet. Sean's master was sculpted by hand long before Hobbyist 3D printing became common place. His helmet is not based on any 3D files out, as his work predates any of them. Even current file makers who make ODST helmets will not readily be able to swap visors between the them as each individual maker will have slight differences in their sculpt, physical or digital.
The best bet might have been to buy one of the Visors Sean himself sells, as they were designed to fit his helmet already.
If you want to print and make your own, you can definitely looked through the free 3D Model index here on the Forum and find one of he ODST visor options, just understand it might not be very compatible with Sean's helmet and you might have to make some tweaks, cut it down, or fill some gaps when using it with that helmet.
3D printers are rapidly becoming a prop and costume builders best friend and many of the members of the 405th are extremely talented at developing high definition and accurate models for printing. This thread is an index to help both new builders find quality models and showcase the hard work of...
