Hi! I am making a filter instert that slides into the back of an aquarium filter. It is not much larger than the palm of your hand really... Height: 6.5 inches or 16.5 cm Width: 5.85 inches or 14.7cm Depth: 0.5 inches or 1.5cm And I have made it as hollow as I feel it can be to be structurally sound. Yet no matter what I do, the price point comes out at insane numbers. This should probably cost 12 dollars, not 120 dollars. I have attached my model as a .dae file and .skp file. I am totally at a loss as to what mistake I made that seems to have the volume so high, and thus, the price. Any and all help or advice is greatly appreciated. This is my first ever attempt at 3d modeling, so I'm sorry if it was a stupid or obvious mistake.
