Sauce Bottle Funnel

This is a quick funnel I made to make refilling a bottle easier. Since the funnel has a non-threaded “cap” that goes over the top of the bottle, it's easier to hold the funnel and bottle in one hand while pouring from the larger container with the other. It has a large top “bowl” to help prevent over-pours or spilling. My print has a bunch of bumps in it. I think this is due to a combination of factors: setting the seam to “random”, the angle of the bowl causing too much overhang, and using PETG instead of PLA. Any tips (or confirmation that I'm right about the issues) are appreciated. If you remix this, please do not charge for it. I think this can be considered an assistive device and I would prefer open access to the idea.
