Cool! I have one too. I haven't been able to find the small Sterno cans. The small ones available now are a little too big. I have an alcohol stove that almost fits. I think I need to find a can the right size and make an alcohol stove that fits.

I have a pop can stove that fits in slick, and really works well. https://www.ebay.com/itm/323687853065?ViewItem=&item=323687853065
