As I broke my Firemaple's stand, was looking for similar printable model, with no luck. It is designed close to original part. It should fold to fit inside the pot. Here some specs from their website:
With the Canister Stand, it's easy to use FireMaple stoves on uneven ground.
It's simple to carry because it's small and light. If you want to save some space, you can fold this up and put it in the pot.
Suitable for G2 G3 G5 gas canisters
