This type of enclosure is built around LilyGO® & SoftRF T-Motion LoRaWAN GNSS tracker board.

NOTICE: This design is applicable for revision V1.1 (pre-production sample) of the T-Motion. Other revisions may or may not match.

It is recommended to start with 'Slim' variant of the design.
It has almost no space for 'extras'. However it gives an access to the board pin headers and BOOT button.

There is an alternative design for the lid of this enclosure to fit for 0.96" OLED I²C display

and an alternative design for main 'body' to give some space for:

• 402030 Li-Ion battery and/or
• I²C BMP280 barometric pressure sensor.

3D print three STL files from this folder: Body, Lid and Cap. You may pick some printing advisories on my Thingiverse page.
If you are unable to print the parts by yourself - you may consider to find an appropriate local 3D service provider and place an order with assistance of Treatstock or 3DHubs portals.
