CO2 Gadget Boxes, 3D Printed and without 3D printer

Last modified 3 weeks

A 3d printed box is the perfect complement to the meter CO2 Gadget although, as you will see, this is not the only possible solution and there are also boxes that are easy to make, even if you don't have a 3D printer..

You have the "official" eMariete boxes and the user-created boxes, so the choice is huge.

Depending on the intended use of the meter, the display, the sensor or the battery you can choose the perfect case, which will give your set up a near-professional level.

Here you will find some samples that you can print directly, with the necessary files to do so, or that you can use as a inspiration or give you ideas for your assembly. Some of them you can even modify them easily from the browser.

JOIN US: If you want your box to appear here, send me the link and some pictures and, if you want, accompany it with some of the following brief description. You can do this through the Telegram group. The only requirement is that it is intended for the CO2 Gadget project of this blog, no matter how many modifications it has.

Official" eMariete boxes

These boxes have been created as a starting point to accommodate most projects and are easily modifiable, should you wish to adapt them to your own needs.

eMariete compact sandwich box

This box is designed with the idea of building a small and compact CO2 Gadget meter that you can take anywhere, with the possibility of battery power.

The components used are: A TTGO T-Display Board with TFT colour display and a Sensirion SCD30 Sensor.

You can download the files for print the compact sandwich box on Thingiverse.

The box has been designed in Autodesk Tinkercad which makes it very easy to modify so that you can adapt it to your tastes and needs. You can find the compact sandwich box in Tinkercad, if you want it modify.

Please note that this box is a very compact design and that, due to the heat generated The temperature and humidity data will be wrong due to the electronic components (although you can partially solve this by adjusting the temperature offset in the CO2 Gadget settings).

You have a complete tutorial for the assembly of this sandwich version:

eMariete TTGO T-Display 18650 eMariete TTGO T-Display 18650 Box

This box, slightly larger than the previous one (although still compact) is designed to use an 18650 type battery, which gives CO2 Gadget more autonomy, as well as being economical and easy to obtain.

It also uses a TTGO T-Display Board with TFT colour display and a Sensirion SCD30 Sensor (in sandwich or normal mode) but, as it is a larger box, you have space to install other sensors.

You have already available the version of the box to install SCD30, SCD40 and SCD41 sensors, soon you will have a second version (the back cover, the front is the same) designed to install MH-Z19, Senseair S8 and Cubic CM1106 sensors.

You have the eMariete TTGO T-Display box for 18650 in Tinkercadif you want it modify.

You can download the eMariete TTGO T-Display box for 18650 at Thingiverseif you want it print.

I am recording a tutorial with this box. As soon as it is finished you will find it here with better pictures.

If you modify it, I'd appreciate it if you could share your version so that other users can benefit from it if they find it useful. Thanks for sharing!

eMariete enclosure for Lilygo TTGO T5 and Sensirion SCD41 sensor

It includes a space to house the SCD41 sensor with air inlets and isolated from the rest of the case to avoid as much as possible that it is influenced by the heat emitted by the electronics and that the temperature measurements are not affected (or, at least, to reduce the effect).

You have two backs for the box. One is designed to fit an 18650 type battery and the other, with less depth, is for narrower batteries.

You can find it at Tinkercad to download or even modify it to suit your needs.

You have the tutorial to assemble this low consumption meter (up to three months of autonomy) in the following post:

User designs and adaptations for 3D printers

Boxes and adaptations by Sergio C for T-Display S3 with various sensors

I love this box. A great design by Sergio where everything fits perfectly. Ready for SCD4x sensors, battery and buzzer. You can find Sergio's box for T-Display S3 at Tinkercad.

Version for the small plates from AliExpress with SCD40 or SCD41.

Version for the official Sensirion plates with SCD40 or SCD41(the developer's kit).

Boxes and adaptations by Sergio C for TTGO T-Display with various sensors

Sergio has also designed versions of the box for the LilyGo TTGO T-Display boards and SCD-30 and SCD-41 sensors in square and rectangular format with integrated buttons.

You can find the boxes and modify them, in Tinkercad, by clicking on the image of each box.

Sergio has also prepared several very interesting adaptations compatible with the "official" box:

This rear part is designed to make the temperature sensor of the SCD-30 more independent from the rest of the case so that it is not so much affected by the temperature of the board.

Back box LilyGO TTGO-T Display for Sensirion SCD30 CO2 meter + microswitch + 102050 LiPo battery

This is the front, with the buttons punched out and the height of the bezel between the case and the display lowered.

Janek's box for TTGO T-Display, MH-Z19B and 18650

User Janek has created one of my favourite boxes.

With a very clever design, in the form of a slanted console, he has achieved a design for 18650 battery and CO2 sensor MH-Z19B (possibly also valid for Senseair S8 and Cubic CM1106) that is still very compact despite the large battery.

By the way, if you try it with the Senseair S8 and Cubic CM1106 sensors, let us know how it went in the comments at the bottom of the page.

You have the Janek's box hereif you want it print.

Ernesto "Cute Cloud" box for TTGO T-Display

Ernesto, @erguro1973, is a regular contributor to and a very prolific creator. His "Cute Cloud" box is an inspiration, capable of integrating into the most unexpected environments.

You can download the Cute Cloud" box for CO2 Gadget on Thingiverseif you want it print.

Carlos M Box for TTGO T-Display and SCD30

Carlos provides them with an adaptation of the official extended box in order to be able to use a 18650 battery.

You can download and modify Carlos M's box from Tinkercadvery easily.

Joe Box for TTGO T-Display, SCD30 or SCD41

Our friend Joe brings us two very interesting designs.

First of all, the adaptation of the box to be able to build the meter with 18650 batteries. A bigger box, with more space.

Secondly, a variation of Sparkfun's SCD40 or SCD41 sensor box (click on each image to enlarge).

You have available the Joe's box in Tinkercadif you want it edit to suit your needs.

You have available the Joe's box on Thingiverseif you want it print.

CanAirIO box for TTGO T-Display. Multiple sensors

The CanAirIO Project Friend Box is fully compatible with CO2 Gadget. It is a large box with space for several sensors, including a particulate matter sensor.

You can download the CanAirIO box from Thingiverseif you want it print.

User boxes without 3D printer

Polypropylene box Sergio C

You don't have a 3D printer, who cares!

With cheap and simple materials that don't require any tools, Sergio shows us how to make a very interesting box.

With materials such as polypropylene sheeting, the kind you buy in the Chinese for handicrafts, and a bit of manual skill, you can create a box in no time at all.

If you want to build a box like this, you have here a complete step by step tutorial:
