All you'll be needing are a pair of working gloves and a flat surface, a table works just fine.
For the legs I've used stainless steel strips . Make sure that the two strips you're using are of the same size, else you'll end up with a crooked fire pit. Width however does not need to be the same.
The square plate on which the logs will be placed is also stainless steel and has a constant width of 30cm.
This fire pit was designed to use a metal processing/container reparation factory's stainless steel leftovers (long strips and rectangular plates), and be manmade without the need of any tool.

Step 1: Preparing the Strips and Plate
1. Start with preparing your strips by measuring them.
2. Calculate the x-variable by taking the (length - 160)/2 (in this example; (270 - 160)/2 = 55)
3. The y-variable (or width) will help you define your punch diameter. Roughly you want 4-5 punches (with 3-5mm) across the width in order to achieve an easy bend.
4. When you're done calculating and measuring you can start to mark on your strip whe there the punches will go. After that you are all set to apply the punches to the strips.
5.The square plate needs to be 30 x 30cm with a punch in the middle
Step 2: Folding the Fire Pit's Legs
It's best to start in the middle of the strip and work your way outwards. By starting in the middle you'll avoid confusion when bending by having a clear view of the progress.
1. When bending the first two bends, make it so that they are not perpendicular to the ground, instead place them under a slight angle.
2. After the first two bends, you'll need to bend the sides that'll touch the ground and provide support. It's crucial that the two bends you're about to make end up flat on the floor.
Step 3: Folding the Fire Pit's Legs
3. This part is probably the hardest, since both legs need to somewhat be under the same angle. I spent a few minutes adjusting after bending before I got a result I was happy with. Remember that shorter strips will be under a sharper angle as to achieve the same result. Mine were under an angle of about 70-80 degrees.
4. The small bends that are going to support the plate are best bend before doing the inwards bent so that you don't have to struggle bending it in a hard-to-reach place.
5.The final bend is a sharp bend inwards, this section of the strip is best placed perpendicular e
6. Repeat the entire process for the other strip
7. Assemble the two strips and the plate by using the small tube.
Step 4: Flatpack (outdoors) Fire Pit
This flatpack fire pit made from stainless steel strips and plate is made from scrap metal from a metal processing/container repair factory. The huge plates of which the strips were part of are used to make the typical indentations of a container, therefore I implemented a small design feature which resembles those very indentations linking the product with it's past, and it's present.
