Dang it. Just barely missed the print being small enough to fit in a common SLA printer. Some of the new resins are just shy of PLA in toughness and print quality would be outstanding most likely. Its also possible to SLA a lens cover for the unit as well as a silicon button set.
BTW thanks for your hard work on this setup - really cool design.
I was just thinking a 3d printed mould of this case to cast epoxy would probably look pretty cool.
If you get interested in redesigning for an SLA printer (Photon Mono probably) let me know.
The print quality should be very high, and likelihood that waterproofing would work out good is pretty likely as well.
It wouldn’t take too much on the main design - probably be able to get it by moving the lanyard loop at the top to be a set of ears on the right and left and bringing in the tripod mount some to take a thin nut instead of a thick one and tucking the board a little further under the GPS module.
I’d be happy to try an SLA print of it afterwards and display the results.
when will you release the case files?
Next couple of days, i just need to finish the antenna clip so it works on both styles of boards.
There is a very high likelihood that I will design a waterproof case for the new TTGO Echo for use with SLA printers.
The features I am thinking are:
surely buying you a coffee would be ok ?
POSTED. I haven’t actually printed this myself yet, but everything should fit.
So far looks good. PETG from PlastyMladeč, .2 mm layer. This evening I will be assembling all parts.
@b8b8 great job! I have some suggestions:
Is this big enough platform? https://www.amazon.com/ELEGOO-Motherboard-Removable-Impresora-220x220x250mm/dp/B08T8RSGR2/ref=sr_1_3?tag=georiot-us-default-20&dchild=1&keywords=elegoo%20neptune%202&qid=1621512035&sr=8-3&ascsubtag=tomshardware-us-1190800903533168400-20&geniuslink=true
Yes that will be big enough, the creality ender 3 is generally the most recommended as a low cost printer.
@b8b8 love the cases you have designed, both the layout and thought that has gone into making them. Thanks for sharing with the community. I also do like the magnetic chargers as they “seal” the unit better and are less fiddly than trying to get a usb cable in and out (these USB plugs are never standard dimensions for the plastic bit behind the connector anyway).
The one drawback with the magnetic charger is that it doesn’t allow software updates easily, and with 5 units I spend a lot of time disassembling and reassembling for testing.
However I found some magnetic connectors with 4 pins that seem to be able to do USB tx/rx as well as charging:
Would this be an option?
You should be able to print it slanted diagonally upwards on the bed with support. Of course this will make a sloooower print, but hey 
I looked at those connectors, however the 4 contact ones seemed to be the least reliable so I’ve been going with the charging only option (that also can swivel). Luckily there is wireless firmware upgrades (still difficult for testing since you cant downgrade).
Working on a new design for the Heltec Lora 32 V2 using 12mm aircraft connectors to make a custom USB charging and DATA cable.
I had to make a few adjustments for it to work for me, but I liked the look of the original design.
I am not super sold on the Heltec hardware, so it feels like a bit of a waste of time for myself, but for anyone thinking about using them, you may find it useful:
