The enclosure is a 3D printed, snap fit case that prints with no supports.

It consists of three parts:

  • co2_topLid
  • co2_botLid
  • co2_mainBox

The files can be downloaded directly here or through Thingiverse.

The top and bottom lids are removable to allow for easy access to the SD card and electronics.

The case has mounting holes for the FeatherWing Doubler and the SCD-40 STEMMA sensor.

There are cutouts for the on/off switch and the Feather RP2040's USB-C port so that you can charge the LiPoly battery or update the code.
