I have seen several versions of this, both as owner built, and for sale items.
In short, the idea is to have a little “table” that gets strapped to a tree trunk and allows you to use your cat food can stove up off of the ground. This proof-of-concept is a little narrow at only 6 inches, but I’m figuring that in a final size of about 8″w x 10″l, in aluminum stock and with a 4′ pull-thru tensioning strap and buckle, it ought to be good to go.
I am also wondering if a version could be made using standard carabiners. This doesn’t have to support significant weight.
More dollar store stuff taking the place of expensive materials…
