lunch bag 3d model

can you make me a compartment below the bag with small fan for regulating the temperature, and in that compartment is divided into two sides which is upper and lower sides. In the upper side, there is a zipper above for the attachment in the bag and for solar panel and switch. while in the middle is a space enough to put a device for the prototype, as well as, making the fabric flexible for easily fitting perishable foods either side of the compartment. Then in the lower, for the regulation of temperature with the small fan just like what I said. Don't make it too big, just enough for food storage.
