UK PETG supplier



I'm assembling the parts for my ROV, and am having trouble finding a supplier for the battery tube. The BOM says use tubing from Mcmaster Carr, who only supply in 6 foot lengths, and dont ship overseas!

While i understand that might be buying this stuff in large quantities, please spare a thought for those of us who only want to build one ROV, and have no use for the other 4 1/2 feet!

once i have found all the parts, is there somewhere where i could upload my UK supplier list, for the aid of other UK users?
