Self-Extinguishing Candle
For my final project in Stanford's ME318 Computer-Aided Product Realization, I designed and fabricated a self-extinguishing candle holder. By using a simple, store-bought kitchen timer to snuff out the candle, I left myself plenty of room to design and fabricate a less traditional brass candle holder. By first cutting a single flat sheet of brass and later bending it to the diameter of my candle, I easily fabricated this rounded, sweeping form on a vertical mill. The snuffing mechanism itself took multiple prototypes and some fine tuning such as swapping out the intended brass plate for a much lighter aluminum one which the timer still barely lifts. The completed holder, polished to a reflective shine with Brasso, takes about 45 minutes to close and then gently extinguishes the candle flame.
