Outer can is 11.5 cm high and 9.7 cm wide while inner is 10.5 cm high and 8.5 cm wide. Eight 12 mm air inlet holes on the outer can and eight 8 mm holes on the top of the burn chamber, loads of slightly smaller holes on the bottom. Nothing was measured, just eyeballed the lot.

The whole thing fits in a Snow Peak Trek 700 although it is slightly too high to fit the lid.
Pot stand comes from a Swiss Army M71 Emergency Stove, which is basically a can of Sterno. Wraps snugly around the burn chamber in travel mode. This might be replaced by a lighter one made from a can.
Stove weighs 103 grams and pot stand 21.
