Drink Chiller Hello, This is my design for a drink cooling device, inspired by a video from RCLifeOn on YouTube. The original video explains the contraption's operation in detail, so I won't repeat it here. However, I did create a video demonstrating how my machine works: https://youtu.be/0sOHWHl4jWI This device uses ice-cold water to cool cans or bottles by spinning them rapidly through centrifugal forces. The warm liquid is drawn to the can's wall and cooled down in the process. It takes about a minute for a 330ml can to drop from room temperature to refrigerator temperature. All parts are designed to be printed with a layer height of 0.2mm, except for the pump housing which requires supports. The electronics box measures 249x134mm. List of Parts (Not 3D Printed) - DC Motor: Igarashi 12V DC Motor (available on eBay) - DC Motor Speed Controller: also available on eBay - DC Switch: Amazon link - DC Jack: Amazon link - DC Power Supply: at least 2A with a 5.5X2.1 plug - Rod: 10mm stainless steel or wooden dowel - Bearing 608 (one piece) - O-Ring (four to five pieces for increased friction) - M3x40 Screws (four pieces) - M3x15 Screws (two pieces) - M3x6 Screws (four pieces) - M2.5x10 Screws (optional, four pieces) - Tube: 115mm with a 9mm outer diameter - Cables and glue The rod has an 8mm diameter on one end for the bearing and a 9mm diameter on the other end to fit the body's hole more easily. It also features a 2.3mm hole for the motor shaft. Instructions: - Print parts with 0.2mm layer height. - Enable supports for the pump housing only. - Use at least two perimeters, three being better. - Infill between 10 and 20% should be sufficient. - Press-fit the bearing into place. - Perform simple soldering when wiring the device. - Ensure the rod turns counter-clockwise while the pump turns clockwise. Assembling the Pump: 1. Mount the motor to the pump lid. 2. Attach the impeller to the motor shaft with super glue. 3. Glue the impeller to the housing. 4. Secure the pump to the main body with the hole facing upwards, ensuring a tight seal with enough glue. When installing the tube, apply a small amount of glue to prevent water from leaking onto the motors. Closing Words: If you have any questions or suggestions, feel free to contact me. I hope you enjoy my design and consider supporting me through tips. It's not required but greatly appreciated and helps me finance my studies.
