Source for timing belts

Looking for a recommendation for a source in the UK for the gt2 timing belts mentioned in the BOM (158mm & 202mm).

I’m not too keen on buying a length and attempting to join.

thanks

Hello, you can source those parts in many shops selling 3d printing parts and also in aliexpress and amazon. I cant recommend you a particular shop in UK but I am sure that you can find if you make a google search.
cheers
