My wood-burning titanium campstove

It weighs 100 g and requires no special fuel

This stove weighs approximately 100 grams and takes practically no space at all. It is made of titanium, which is lightweight for its strength, and can withstand the high temperature of a wood-burning fire. Aluminum would also do fine, but it melts too easily.
It packs away flat, and is assembled in a minute. The stove has four walls and a raised bottom, and is designed to be used with a pakki, a tall, slightly flat cooking pot popular among Finnish hikers. I think it's called a "mess kit" in other languages?

To assemble, first attach the two sides to the back. Spread the sides a bit to insert the bottom. Finally attach the front, which locks everything else in place. Of course, when first heated, the sheet metal twists completely out of shape, but the locking tabs do work even so.

Here's the stove in use, burning dry twigs. It can also be used with a Trangia spirit burner, which may be used indoors or under a tent flap, but the less fuel you need to carry with you, the lighter your backpack will be.

The stove works just fine in windy weather, but with no wind, you'll end up blowing constantly in the fire to keep it going. The fire space should be a couple of cm taller, which would make it burn easier. Also, a lot of tar and other unburnt residues condense on the pakki, making it sticky and rather messy...

If you want to make your own stove, here are the drawings. (Sorry the dimensions are missing! But if you print onto A4-size paper, the drawings will be actual size.) I strongly recommend you make the fire space higher, though! I designed mine so that the distance from the Trangia spirit burner to the pot is the same as in an actual Trangia, but I think that was a bad choice. After all, twigs are the primary fuel, the spirit option is only as a back-up.

If you can't obtain titanium sheet metal, try stainless steel (but not galvanized steel, as the zinc it's plated with is toxic). Aluminum is fine if you will only use a spirit burner, but it will melt if you burn wood in it. It should be ok for hexamine/Esbit fuel, though, since even beer can aluminum will withstand that heat. You do know the nasty byproducts formed when hexamine burns, right?
