More spacious leg for gas can stove stand

Print three of these legs, and then one middle part of the original model.

The model was crudely edited in blender, so there are no clean measurements, I just happened to get a pretty good fit on the first try.

The grooves for the gas can bottom lip are both deeper and a little bit towards the outside of the leg. I'm not sure if the gas cans are different around the world, but this modification works well for my canisters.

I also made the leg a little bit shorter, so that they fit nicely in my MSR pocket rocket kit.
