Well that’s annoying, managed to snap my Y axis belt where the copper/brass buckle is. Amazon have spares so I’ve ordered 2. This was on my V3 SE. Did look at some of the 6metre kits but ferrules seemed to be a problem sourcing.
You can use a zip tie for now.
If you mean these, search for GT2 Belt Clamp on Aliexpress, Amazon etc.
Cheers I shall get some of those too.
Zip tie? How?
