First one of each will be the most expensive because they have to make the mold etc. but after that, assuming you get orders for the same adapters, you could be retiring in Vacuum heaven!

mold? I was thinking of ones made of carbon fiber. This is for Dyson, after all. Who will put up with a $1 part (it being a non-Dyson part, it cannot command a $30 price).
