I have a #3DModel of the #LoRa #radio #solar node that I've been working on for months.

At the top are the mounts for the DFRobot MPPT board with the RAK 19010 board just below it. The big empty space is for a battery pack (4x 26700s).

Of course now that I'm posting this I realized that I want a second battery pack, and I should probably have holes for the solar to come in and antenna to go out. Oh and a short divider so the battery pack doesn't ram into the RAK in transit would be nice.

But am I going to delete this draft and make it look like I did it perfectly the first time? Nope. Post your failures. Own it. Keep it real.

Is the channel in the rim for an o-ring?

First I'm going to try a slot & groove for the lid. I expect that will keep moisture out.

If I'm wrong, It can be used for a gasket but then I'll have to put some ears on it to bolt it shut.

Oh gods. Now I'm learning about the 5 different dimensions in every standard shaped grommet only to find that normal retailers only provide 1-2 meausrements and they are ambiguous about which diameters/widths they are.

Guess I'll be buying a sampler pack and using the calipers then... 🙄
