A 3D printable case for Sensirion SCD-41 CO2 sensor, QT Py ESP32, and Nokia battery.

I first mocked up the layout in 2D using InDesign, then moved into FreeCAD for the 3D design.

I've also made an alternative case for the SCD30 CO2 sensor and Sparkfun Thing ESP32 - see v3.

I used Shapr3D on the iPad to create a more freeform case. See /shapr3d

The entire family of Shapr3D cases:

• Arduino code for ESP32-C3 QT Py
• iOS/macOS app

• Increase ESP32 compartment by ~0.5mm
• Add USB-C charging slot
• Increase hole in lid for on/off access
• Fix SCD-41 mounting position
• Add smiley face ontop cover
