Knowing that Hanukkah starts this week I designed and printed this menorah that uses tea lights. I'm not Jewish myself I just have many close friends who are. To all my Jewish friends a Happy Hanukkah!
For those with concerns about heat and these candles let's try using science and look at the last image. This candle has been burning for 45 minutes and is completely liquefied. The apparatus is my Fluke meter and a temperature probe. The probe is sandwiched between the metal base and the holder. The temp read is 53C. PLA goes to glass between 60-65C. ~ There was no deformation from the candle. My candles are from Ikea and the wicks stay centered.
The typical Hanukkah candle is burnt for 20 minutes. Never leave an open flame unattended.
