Đường đua lửa bằng lighter fluid – vui với lửa

ATTENTION This is a super fun teaching toy, but you are literally playing with fire. My first print burned to a sludge because I had too much gasoline in it. But I did it on a large non-flammable surface and had water and fire extinguisher nearby. No problem in my case, I just let the gasoline burn itself out and then blew out the burning PETG. Ideally do it outdoors and have sand, a blanket, a fire extinguisher, or similar at hand! ATTENTION
