About this 3D model

Purchased Parts: 1. Any stainless steel cup with a diameter less than or equal to 73mm and a height less than or equal to 85mm (for holding alcohol). 2. A quartz glass tube 300mm in length, 60mm in diameter, and 3mm in wall thickness (the length of the quartz tube can be less than 300mm, depending on personal preference, preferably between 100mm and 300mm; do not alter other dimensions) (reference price: 100 yuan for a 300mm length). 3. High-temperature resistant cement specifically for furnaces (fire-resistant cement...), preferably mixed with aggregate (reference price around 45 yuan for 5Kg). 4. Industrial alcohol 99%. 5. Matches, a torch, or a camping fire starter. 6. A shovel for mixing cement, a plastic basin for holding cement, safety gloves (both labor protection and latex gloves), a 3M respirator (or KN95 mask), and a vibrator (such as a massage gun) for removing bubbles internally (alternatively, you can use a hard object to tap on the outer wall of the mold). Self-Prepared Items: A set of 3D-printed molds. Operation Process: 1. Print the molds. 2. Pre-assemble the molds. 3. Prepare and mix the cement according to the instructions. 4. Pour the cement into the molds. 5. Remove bubbles using vibration or other methods and replenish cement as needed. 6. Allow the cement to set (specific time depends on the cement instructions, generally more than 72 hours). 7. Remove the molds using any means necessary, such as a heat gun, soldering iron, pliers, scraper, flathead screwdriver, etc. 8. Pour alcohol into the stainless steel cup and place it in the center of the real cement base. 9. Place the cement base on top of the real cement base (assuming there is a base for supporting the cement structure). 10. Ignite the alcohol. 11. Cover with the quartz glass tube. 12. Enjoy the warmth and watch the blue fire tornado. (The English translation is machine-generated, and in case of any ambiguity, the Chinese version shall prevail.)
