Just for completeness, here’s what the various soaker hose clamps look like in the garden, as solid models only let you visualize the ideal situation:
This one prevents a puddle in the path to the right:
Bending the hoses around the end of a bed puts them on edge, with this clamp suppressing a shin-soaking spray to the left:
The clamp at the connector closes a leak around the crimped brass fitting, with the other two preventing gouges from direct sprays into the path along the bottom of the picture:
All in all, a definite UI improvement!
As far as I can tell, we have the only soaker hose repairs & spritz stoppers in existence. Hooray for 3D printing!
The Smell of Molten Projects in the Morning 
I’m going to bookmark this because I cleaned out a Lowes and a Home Depot of all their soaker hose. I bought 450 feet of the stuff and I still need about that much more.
The hoses are absurdly fragile / brittle / cantankerous in (what I think should be) normal use. I made up enough of a surplus to staunch the usual leaks & sprays for the rest of the season; the clamps have already paid for themselves several times over.
I wonder how long until most of the hose is 3d printed clamps….
Well played!
The showstopper will be a complete fracture across a hose, because (IMO) no feasible clamp can hold the ends together against 100+ psi water. But, hey, until then, I have a lot of aluminum sheet …
