10mm GT2 Belt clamps

I saw a few people upgrading their X-Carve to use stronger belts. The belts and pulleys are easy to get but how about clamps for 10mm wide belts? You still need to attach belts to your machine once you have them and the standard ones that come with the X-Carve kit are too narrow. Anyone know where to get some?

Phil has them for the 9mm belts
