Why Is My Design So Expensive To Print

    My design isn't that big and i'm selecting the cheapest material but its still like 300 dollars.

    Can you be a bit more specific (which material, what size, at least some general idea what the design is) ? Printing is a very time- and energy-consuming process, so things that appear "not big" in the context of common household items can turn out very expensive, especially when compared to injection-molded plastic parts where the manufacturing cost is spread over tens of thousands of copies. That said, one possibility is that your design is solid where a hollow part would work just as well and use much less material - this can also happen with a part that is designed with an interior void that is not connected to the outside.

    What are you calling "not that big"? How big is it?

    In the world of 3d printing, complexity and uniqueness are offset by the fact that it takes a LOT of electrical energy to run the machine. Things tthat are "reasonably" priced for the injection-molded world are pricey when printed in 3d.

    We'd have to see some more of what your actual model is, or some dimensions for it, but I'm guessing that you're around a foot long and 4-5 inches in diameter.. that "big" in the 3dp world.

    5mm walls is probably a bit more than necessary, and 24x10x8 unfortunately is quite big for something that is lasered together from specks of nylon dust. If this is a box with a lid, or just an open container ?

    You should consider making the box out of some other material like wood and just print the clips if possible. That's a huge box for 3D printing.

    You can minimize cost by

    thinning walls,

    putting a matrix of through holes in the walls if possible,

    rounding all 90 degree corners to a radius of about 20 millimeters,

    or if you don't want rounded corners design the box so it it fold into a box, maybe using hinges and fasteners or glue to hold the shape.
