This is a super niche ask, but does anyone print (and is willing to share a file) or know of a company that prints adapters for pump sacks?
I've got a Therm-a-Rest pump sack I absolutely love. It's seam-taped and waterproof with a wide opening (that cinches) so it doubles as a pack liner. I also stuff my clothes in it for a body pillow. It weighs very little (less than a compactor bag) and is more durable than nylofoam.
However, I also backpack with my 4-year-old about 1/2 the time. We just got my kid a Nemo Tensor pad (upgrading her to adult stuff). And the pump sack sucks. It's tapered at the top, so it's utterly useless as anything else. I have to carry her gear, so every ounce counts!
I'm wondering if anyone has bought or can develop an adapter that would fit into the Therm-a-Rest pump sack (female) and then can be screwed into the threaded Nemo Tensor (male) so I can use the same pump sack and just have a little adapter. Also open to any ideas for how I could MYOG it from the parts I've already got.
Sure, I could just blow up her pad. But I'm above 12k quite frequently, and she likes to use the pump sack to "do it herself." So there's that.
I do not own a 3d printer, but I have access to one via a neighbor or I'm happy to support a cottage shop.
I went searching the web and couldn't find anything relevant.
