This funnel is only 42mm in diameter and 55mm long. The nozzle is 20mm long and 6mm in diameter. It's perfect for transferring liquids such as perfumes/fragrances or facial toner to smaller bottles e. g. for carry-on luggage or travel-size bottles. If you print this with 0.2 mm layer height, the walls should be only two perimeters wide. A fairly slow printing speed is recommended. You'll not need support material. Please note that you can use almost any liquid with this funnel if you print with ABS, except acetone-based liquids like nail polish remover etc. You can make it glossy and smooth by treating it with acetone vapor.
