I redesigned this awesome Jerry Can Clip to fit oval spouts…which seems to be the most common type.

There are a few variants to the old WW2 German Jerry Cans. The spouts are also a bit different depending on where you buy your can. I have two or three variants myself in my shop.

The Fusion 360 file is included and all measurements have been parametized to make changes to your own specifications almost instantaneous. See the YouTube video for instructions on how to make any changes you may need.
