Radiator drain plug question

[Uwe Blab]

Has anybody come up with an adaptor for the radiator drain plug? Right now it drains like somebody is putting their thumb over the end of a hose. Makes it hard to collect into a milk jug. Plus it gets all over the frame and anything else in a one foot radius.

I'd prefer something that has a narrow downspout with a thumb screw on the side to open and close the flow.

Thanks in advance for any help or suggestions.
