<div><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><br>- code<br></div></div><div><br></div><div><br></div><div>Sep 24, 2021, 03:10 by taylorhayis@icloud.com:<br></div><blockquote class="tutanota_quote" style="border-left: 1px solid #93A3B8; padding-left: 10px; margin-left: 5px;"><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.

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></blockquote><p class="">Sam<br></p><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></p></blockquote><p class=""><br></p><div>On 24/9/21 7:10 am, Code Bus wrote:<br></div><div><br></div><blockquote type="cite" class=""><div class=""><div>What enclosure are you referring to?<br></div><div>If you mean the one featured in the video, you're free to make
