I designed this fire puzzle off of the puzzle in the Survivor TV Show. You can print them in different colors and see who can solve it the fastest. I used 0.24mm layer height, 0.4mm nozzle, 8% gyroid infill. They print great. On my machine I can print it as one plate all connected and they come right apart. You might have to wiggle them a bit to separate the first time. Uses about 280g of filament and prints in 7 hours.
