3D print doesn't provide much environmental protection, which is what's
needed.
I've put a few of mine in $6 plastic 'tackle boxes' from hardware or
fishing shops. More room for extra 18650's, waterproof, etc. Still
slight problem with button-pushing, but I did add a mercury tilt switch
to one, to overcome that. Experimental still.

Yes, I meant the one on the video.
3D printing is a totally fine way of doing an enclosure in low
volumes, but is a massive difference in both reality and "cost"
between buying something on Alibaba or just via paypal from
someone who has built them before, and something only available as
a CAD/3D printer file. I've gone through the process of finding a
3D printing shop, and getting something made, with a less than 50%
success rate, and a one-off is always more expensive as even a
good shop has to allow for the likely cost of getting it wrong the
first time.
One of the advantages disaster.radio potentially has over some of
the other solutions its the potential for geek-free setup and
install. I can figure it out, but most of the villages around here
- who could use a setup like disaster radio - don't have a
resident geek, and trying to find a 3D printer to print a one-off
certainly puts it in the needs-a-geek bucket.
The enclosure Sam suggests sounds a better candidate, though it
needs the panel mounted separately.

I'll try that enclosure you suggest - its a good price. But I'm
wondering, have you tried using one of them with the other parts
in that part list? How did you handle mounting to and getting the
aerial out, Are those connectors the right size for that, without
looking in detail at the components I'm guessing it would want the
small connectors for the solar panel cable but its unclear if the
4-8 or 9-12 connector would be best for the antenna proposed - I
think the smaller (the antenna says 8mm)

What enclosure are you referring to?
If you mean the one featured in the video, you're free to make them
yourself. The design exists as CAD and in 3d printable formats in the
github repository. It is not less "real" simply because it hasn't
been mass produced.
Otherwise, like we've suggested, you can follow the Aliexpress parts
list and make a working device, or use any enclosure designed to
prevent water ingress.

Thanks Sam
I was looking at the enclosure shown on the image on
https://disaster.radio/ and thought that might have been real :-(

Can you clarify what the current state is - i.e. if I got
the boards, built a pair of units, and flashed it - then
would the chat and map apps talk over it.
Yes that should be possible. You can buy them pre-flashed if
you want to miss that step:
https://www.aliexpress.com/item/4000396836096.html
If using the webapp you only get a chat.
If you use the Android app then you get a chat and a map AFAIK.
By the way ... I notice there is a bad link to the
enclosure on https://disaster.radio/build/
Thx started fixing that link here:
https://github.com/sudomesh/disaster-radio-website/pull/12
awaiting someone to approve.
This was the enclosure used:
https://www.aliexpress.com/item/4000452268197.html
It's fairly obvious how to put it together, but there are
some instructions here too:

The project lacks a maintainer with enough time to

I've been spending my free time trying to modify the
firmware for the v3 dual-module prototype, it is
slow-going.
Other LoRa boards seem to work pretty well with the
firmware in its current state

I tried to find out what was happening with
Disaster Radio, by
asking here - got zero responses :-( its really
hard to figure out
if there is anything going on that is useful to
connect with :-(

Hi,active list?Grzegorz
Sort of. When people ask, someone answers.
But not much seems to be
happening. I do have the impression that
those on the list wish there'd
be more activity, and that most of them sort
of hope to contribute. I
of course do not speak for the coalition.
Perhaps you can tell us why you're interested
and what you'd like to see
as highest priority.
