Software to make moulds (and maybe other products)

Hi, I am software engineer father of a chocolatier, we have developed a web application to let customers design their own chocolate bars. The idea is that anyone can generate and save her/his design and the chocolatier or the moulder will recieve a file to make the mould.
It is designed for chocolate moulds, but it can be adapted to other applications, this is a proof of concept. Now we are looking for opinions and strategic partners, and I thought that here maybe someone has something to say.
Feel free to comment, please.
Now it is not adapted to mobile screens, minimum a tablet. Here you can try it: DTMould
