# Feather TFT STEMMA Case
## Overview
https://youtu.be/nKFDXzp5-So
3D print a Stemma case for the Adafruit TFT Feather with ESP32-S2.
This dev board features a 1.14 inch display with a Lipo battery charging circuit and battery monitor.
It's has the ESP32-S2 mini module which works with both Arduino or CircuitPython.
We designed and 3D Printed a snap fit case to make a little compact IoT project.
You can easily add STEMMA QT breakouts like temperature and humidity sensors.
The two buttons on the front are accessible so you can quickly reboot or get into the bootloader.
The STEMMA QT connector is also accessible, so you can daisy chain your sensors and make a portable IoT project.
You can 3D print the parts without any support material using your favorite filament.
The bottom features slots so you can use M2.5 hardware to secure STEMMA QT sensors.
You can fit up to two boards and secure them using hex nuts.
A small Lipo battery is able to fit in between the built-in standoffs with the cable routed through the side.
The Feather press fits into the case and the two covers just snap fit over the top.
