Coolmingo - Drink Cooler

Overview:I like tea, but I don’t like waiting for it to cool down before I can drink it. That was the motivation behind building Coolmingo – Drink Cooler. It uses a 5015 fan to blow air across the surface of the drink, speeding up the cooling process.I conducted a test, and the results show that the cooling time is cut in half. Boiling water cools quickly from 100°C to 80°C during pouring, but then cools down slowly in the cup. It took 13 minutes to reach 60°C, which is generally considered a pleasant temperature for drinking. With active cooling, the time was reduced to less than 6 minutes.The fan is rated for 5V, so it can be powered by any USB port whether from a charger, PC, or power bank.With different nozzles, it can be used to cool various drinks and foods. I recommend to print it from PETG or other matariel which will survive hot drink temperature or use PLA but place a coaster under the cup.Bill of Material:4x M3x10mm Countersunk Bolt (optional M3x8mm)Rocker Switch 10x15mm USB
