Prototyping a Heltec T114 case
I have settled on the Heltec T114 as my daily driver and wanted a case for maximum battery life (because I'm always forgetting to charge the pathetic 800mah battery it came with). And it still needs to be sort of pocket size.
I designed and 3D printed a case that holds a 10,000mah battery and a small solar panel. The USB is accessible through the cut out next to the node. The case splits in two parts, top and bottom. The battery drops into its compartment and solar slots in its holder, the top section holds everything in place. There is a small gap behind the solar to protect the cables and connectors.
It needs some more work but pretty happy so far. I will probably add some sort of clip to lock the two parts of the case together. Right now its a tight fit so doesn't come apart unless you pull it, but securing it properly would be best. The node holder might need adjusting (or a tiny blob of hot glue on one corner of the node to stop it pushing back). And the battery compartment has a slight rattle, I didn't want to squish the battery, but can probably do something there to keep it quiet. And it looks a little bland. I'll use it a few weeks and see what else needs changing.
