Garden Hose Funnel

I've had a problem with filling my RV water tank when I'm boondocking.

I created this to be joined to go with a fill adapter (https://www.thingiverse.com/make:776019) and a 90 degree bend (https://www.thingiverse.com/thing:2009236)

Eventually, I'd like to figure out how to make it all in one piece, but my printer is too small, so I made things that are garden-hose threaded, because that's what all the hoses for my RV are set for.
