Battery-Operated HeaterMeter Finished!

Hey guys, finally got this all-in-one battery powered HM up and working. Thanks to Tom Cole for the design of the case, which I blatantly ripped-off for my own design. I know the printing of my case isn't great and the printer will need more adjustments. Everything fit, so it wasn't a big deal to me that it wasn't perfect.

The batteries and charging circuit are from Amazon.

It's wired in a way so that I can power the HM directly from the standard 12V jack, power the HM from the battery by flipping the switch, or charge the battery with HM either off or on.



I like its wide enough to stand up by itself.

Be cool if someone made a case that sat naturally at angle for viewing. Kind of triangular. Simple box rectangle has no necessary function.

Any chance of sharing the STL files for this? It would be great to not have to run wires each time I smoke. also whats your runtime?

That's awesome. Love this. Would like to do as the next project for my heater meter. Just finished a smokey joe build so I'd like another smoker project before spring gets here!

Can you share the stl files?
