As of Feb 2026, this has been refined to be a significantly smaller case that can be carabiner attached to a belt loop.
Replaced the 955565 Lipo battery (5000mAh, overkill for a nRF52) with a 18650 (this one is 2600mAh). Removed solar panel (gimmick, never used)
Flipped board upside down to minimise external dimensions.
Removed external antennas (arose too much suspicion from people around me)

Assembly should be pretty self explainatory.
- Insert Battery
- Plug Battery into RAK
- Stick down Antennas
- Insert RAK board and screw down with screws provided by RAK
- Slide lid on
Another off-grid meshtastic case for the RAK4631
This utilises the RAK WisBlock Base Block with a RAK 4631 Module (nRF52 based LoRa).
3D Print the case with your filament of choice. If you anticipate it seeing more than 40 degree C days, I'd avoid PLA as it can distort.
- RAK Module (comes with Bluetooth antenna)
- 955565 LiPo battery from online (9.5mm thick, 55mm wide, 65mm tall)
- 5dBi Antenna with u.FL to SMA Female cable
- 110mm by 69mm Solar Panel. I got a 5V 250mA panel
I used kapton tape to hold the battery in place, as well as line the inside of the print to reduce chances of puncturing the battery.
BT Antenna was stuck down using M3 adhesive on the bottom of the lowered area, between the battery and RAK WisBlock.

Note the USB C fit isn't perfect, you may need to shave down some sides of it to fit. Printer dependent.
Assembly should be pretty self explainatory. Slot down at an angle and close up. Screw with M3.
