Gasifier rocket stove for laser or CNC plasma

thingiverse

this is a file to make a hybrid rocket/gasifier stove. Cut the parts out, roll, make the top and bottom circles (not included yet but easuly drawn) The biggest piece is the outer shell, the 2 smaller pieces are meant to roll into tubes that fit together in a 90 degree pipe elbow. The advantage of this design is there is no need for insulation, and it is more forgiving to operate.
