A seamless finish is crucial, so make sure to print the entire object in one go without any gaps or holes. To achieve this, set your 3D printer to create thick walls with a height of at least 3mm and opt for an infill density between 10% to 15%. Since you're printing upright, supports won't be necessary; however, it's highly recommended to add a brim to prevent the object from detaching from the print bed.
