Case was built in support of this project:
https://hackaday.io/project/189309-esp32-ntp-time-server-stratum-1

Included are the .stl and (Fusion 360 source) .fd3 files.

 Note: this print were designed for use with the Olimex ESP32-PoE-ISO Rev. B.

 More current versions do not have the same footprint and will not fit inside the case
