Tarnfell Folding Backpacking Stove: Outdoor Product Design Concept

Most backpacking stoves are a loose kit of parts that rattle around in a pack, with pot supports that fold awkwardly or not at all. I designed the Tarnfell to fold down to the size of a fist and pack inside its own pot. Each of the four pot supports swings down on its own pin and parks alongside the stem, teeth facing out. Unfolded, the stove is 163 mm across and 70.5 mm tall; folded, it is 86 x 64 mm. Nested, the stove rides on a 100 g canister inside a 1.2 L pot with the lid closed over both, packing to 114 x 137 mm. The build includes a perforated burner head, a serrated support ring, a piezo igniter, a wire-handle control valve and a fold-out canister stand. What's included: hero and in-use renders, a burner detail, an exploded assembly of every part, a fold-and-nest sequence (nested, folded, unfolded) with dimensions, and four CMF colourways: orange, blue, olive and black. Concept project: Tarnfell is a fictional product. Dimensions and performance figures are design targets, not test results.
