I saw several of the 3D printed solutions and I didn't feel any of those captured what I wanted. So I've created a design that I think solves several of the issues:
# New nut must be able to reuse the old hose (so no need to find new hose, or the crimps).
# Home made with 3D printer, so that if it fails, can re-make.
# The load on the crimp must be uniform around it's perimeter (there are some solutions which only press on half to 3/4 of the crimp, allowing gas to leak from the non-pressed portion).
-
So I came up with a half nut design with an outer case to hold the half nuts together. I've put the design on ++[link|https://www.thingiverse.com/thing:6245585|Thingiverse|new_window=true]++ if anyone needs it. Make it out of PETG for better strength. Tested it and so far seems to work ok!!
