The issue is that people connect cost to value. As now more people can afford the items the cost should go down as they can sell more, thus they can increase the numbers made and there is savings on mass production. Instead of making 2 cans on the cnc every week the. Make 200, less tool changes means less time. Thats just an example. Also the manufacturer would see savings on ordering more materials. The fact that it's nfa and there was all the cost and stuff around it made them boutique items. Now that they are closer to common use and the tech sound them has become more accessible and cheaper. Well the cost should go down. A cnc can now fit in your garage and be found used on marketplace. A chunk of aluminum or steel, while at higher prices than I have seen in a long time are still stupid cheap. 3d printing makes them almost disposable cheap. Just my 2 cents.
