Sure anything can be manufactured made copied, if the manufacture does not have any protection on the product, but for that price of $2 I don't think so, you most likely would not do it in the USA for anywhere near that price ( 1 ) end would cost more that that to manufacture
So what you have to look at is the Flex material can you source it in the USA and how much per unit it will cost, then you have to cut it to length, do you already have a CNC lathe and mill to machine the ends and a crimping machine
