If you have Helltec ePaper with LoRA v1.1 - you can use this case - https://www.printables.com/model/822280-18650-enclosure-for-heltec-wireless-paper-meshtast
For better holding 18650 battery, I designed small insertable bay. There are cut outs for RF antenna cable, USB connector and for display connector. Just print it and insert.
On the top part of named enclosure, break two residual parts (see photo). I did not remixed original, it is much quicker solution ;-).
31.1.2026 - Added large version.
