About

I made a lightweight tray for heating portable gas canisters to solve the issue of using them in cold temperatures. When the temperature drops below 0 °C, the butane in the canisters stops vaporizing, making it impossible to use the stoves. Even if you manage to ignite the burner, the canister's temperature quickly drops, resulting in the flame going out.

The common solution involves placing the canister in a container of warm water while cooking. While there are existing 3D models for this purpose, in my stove (Orgaz GR-823) the canister hangs in the air, so I needed a mount. My tray fits perfectly for the widely used 90 mm diameter canister (see photos) and is easy to attach without tools.

I recommend printing the tray with PETG for the necessary flexibility. The tray "snaps" onto the bottom of the canister. This simple solution allows efficient use of the water's heat, preventing issues with butane turning into a liquid state and maintaining the flame during cooking.

How it works?

  • print (I recommend PETG, layer height 0.20~0.24mm worked for me)
  • attach to bottom of your gas canister
  • fill tray with warm water
  • ignite the burner
  • keep an eye on water temperature as it tends to cool down fast

I hope this proves useful! :)
