For this post, I decided to create something that we all have most likely seen at some point in our lives, a take-out food box. I created it using sheet metal tools as I treated the sheet metal like paper. The neat thing is that you can unfold this into a single piece. The image below shows that unfolded state but I made the bend lines more clear to give you an idea of how this goes together.
The main box was started by using a base flange and then edge flanges were added to create the sides. I used the mirror feature a number of times as the opposite sides are symmetric. I then added a number of cut extrudes and bends to finish it off. Some of the folds I was not able to get perfectly flat against the sides as space was need so that the handle would fit. After I finished creating the main box, I created the handle as an in-context part. This allowed me to make sure that the handle would fit perfectly on the box with not interference. Feel free to check out my model.
