This is a re-mix of my original enclosure for The Things Network (TTN) node based on Adafruit Feather M0 with RFM95 LoRa Radio and Adafruit OLED FeatherWing:

This version is taller to accept the Adafruit GPS FeatherWing in the middle.

The design is optimized for a 0.35mm nozzle and 2mm layer height.
