Hydro Flask Wide-Mouth Funnel

This is the funnel for the Hydro Flask Wide-Mouth Vacuum Water Bottle - 40 fl. oz. bought at REI. This would make the job of putting ice into the flask much easier.
It's a customizer thing, so measure your flask's mouth inner diameter and print one for your size.
Note that I have been using these large mouth funnels for many other applications such as transferring soup to jar, even oil change (not using the same funnel :-). I hope you find it as useful as I do.
Enjoy
