You gave me the comments, I have received, in the knife network to make improvements, you can do several sets of different density blade grid, can be replaced, to meet the needs of mothers cut different sizes of vegetables Ding. The size of the product has also been marked.
You can slice vegetables on the left. And on the right is Chedin.

Hi Jiawen, thank you for the developed version of your design solution. It is nice to have different variations for the blade part, but there are further developments that you can consider because we think that it is still lacking of variations of functions. For example, you can add different features to the blade part like grater, lemon squizer etc. Maybe you can add another lid option for storing in fridge.
Maybe you can consider the stackibility, or non slipping surface for the bottom part…
And lastly, can you give the height of the container itself and the lid part in your finalized version.
We’re very excited to see your finalized design. :)) see you soon!
