<p>It seems to be way too early to do large volume production, but
there would be an intermediate solution if there was a 3D print
shop that could do them on demand, though the enclosure Sam
suggested might be better for smaller volumes. <br>

<div>It is possible now to bring the tooling cost down if the
job shop is set up to use 3D printed low-run tooling. One can
print a mold from high temp resin and get between 50 and 150
parts out of the machine before the mold becomes unworkable.<br>
</div>
<div><br>
</div>
<div>Not saying that's the path which would work well for Mitra,
but it is something to consider asking the factories that you
have a relationship with. Making an enclosure could be
feasible even in low-run production, if there were enough
interest - and a non-WIP PCB :]<br>

<div>For what it’s worth Mitra, in my day job I develop products
- often from plastic. I design injection moulded parts, have a
full CNC machine shop at home including 3d printing, and
relationships with factories in China and Australia. An
enclosure like this is about a $10k tool, and no more than
$0.40 per set (front and back clamshell) with an MOQ of
2000pcs or so.<br>
</div>
<div class=""><br>
</div>
<div class="">If there was a final footprint / PCBA, making an
enclosure wouldn’t be a particularly expensive or complex
endeavour. That assumes someone is going to mass produce these
however.<br>

<p class="">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.<br>
</p>
<p class="">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.<br>
</p>
<p class="">The enclosure Sam suggests sounds a
better candidate, though it needs the panel
mounted separately. <br>

<p class="">Sam<br>

<blockquote class="">
<p class="">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) <br>

<div>What enclosure are you referring to?<br>

<div>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.<br>

<div>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.<br>
