After having issues with other version printing I wanted to take the time to figure out how to make it work. Built the funnel from the cap steps from the original included.
I flipped it to make sure that the top was connected to the bed with a brim of 2 mm to give it additional ability to stay on the bed while printing. I included all the files, but the steps as it did not look correct in fusion 360.
Be more that happy to export, but created two circles on top of the cap after removing the ring on the top. Created a loft from the outer circle to build the form and a cut on the inner circle to build the funnel.
