3d Printed Belts for the MG08/15

Boss man got an MG08/15 and my friend Nik and I were tasked with getting it running.
We started with Turkish aluminum belts, but they don't work at all in our gun. It's theorized the Turks have a special feed block, but not much is known.
I hunted around for weeks and finally got a Vickers cloth belt. It was too loose and dropped rounds. On advice from some older guys on forums, I ran it through the dryer  in an attempt to shrink it. This helped a bit but was not quite enough.
So we embarked into making 3d printed belts. Here's the final result.

They're printed on an FDM printer out of Polypropylene. We tried PLA, PETG, and TPU before the PP did the trick.

Here's the download link for the STL file. Please let me know if the link breaks. I'd also love to know if you use these!
