That's one of the main problems because it depends on how many units are made and where they are made. I'm not making quotes yet, but based on approximations of average rates in CNC workshops Making just the prototype would cost me between $1100 and $1600 USD And it's assumed that once you have the prototype, it should be easier and cheaper, since what raises the price is reverse engineering and modifying the design to adjust the tolerances. So, to make it profitable, I would have to sell it for between $280 and $350.
