Wiper fluid funnel VAG AUDI VW SKODA SEAT

I was frustraded with the way the VAG people expect you to have three hands when filling in wiper fluid on my Audi A4. Two for holding the canister of fluid and one for holding back the fill hole cover. I decided to make a spout / funnel for this. The diameter of the filling hole in the Audi is 45mm so perhaps this fits other cars as well. The idea is that it would be somewhat of a snug fit, for me that has worked out at least with the non spiral vase version. The version shown in the first picture (on the car) had a air release channel, it turned out that there is no use so I did not continue with publishing that version. I recommend printing this with TPU, other flex materials might be too soft. The spiral vase version might be too soft also.
