I've been working on this Heltec T114 case for a while, carried prototypes with me for testing and finally it's ready to be shared.

The cooling fan is automatic, it switches on when the case reaches 40C (104F). Vent holes around the bottom of the case draw cool air through channels behind the battery and the space behind the solar panel.

With the 10,000mAh battery and some solar charging I'm on course to get around 3 months out of a single charge (without the GPS running).

It uses a 1100mAh battery that came with my Heltec V3 node, keeps it lightweight so I can clip the case to a backpack. The top panel clips in to hold everything in place, it protects the USB and helps with accidental button pushing.

I tried to make this easy to assemble so no screws or bolts. The node slides on rails, battery compartment is behind the solar, the only soldering required is the JST cables on the solar panel.
