Had I not lost 20 months of data when my laptop died, I'd have given you a comprehensive list of MYOG (make your own gear) tent and cabin, wood burning stoves.
Perhaps use your computer to search for DIY Tent Stoves, Make Your Own Gear Tent Stoves, Wood Burning Stoves, Cabin Stoves etc.....
Also use the Image Search facility as I've found really good websites this way, which did not appear in the Web Search.
Metal tool boxes, cooking oil drums, catering size tins from coffee and foodstuffs all work. Your local deli, coffee shop etc will happily let you have empty tins for free.
My personal favorite is to use a discarded stainless steel bathroom cabinet, cut down to approximate the size between a Kifaru Para-Stove, and their Small Stove. It also folds flat, and was free!
There is free information online which will suit your specific needs perfectly, Google is your friend!
