Bugman_140 shared this project on PrusaPrinters.org

I separated the capsules and arms from the chassis to allow them to be printed in a contrasting colour if you wish, these parts can all be glued into place with a few drops of superglue.

the chassis lid was designed with colour changes on the printer in mind, I switched for the top details including the speaker and neck rings then back again for the speaker top and grille

I have included mounting holes inside the chassis to hold the Arduino, these need some heat inserts (i used just 2 diagonally) and space to the right for the bread board to be positioned with its sticky backing.

I then also added the 4 x heat inserts on the top edge of the chassis ready for the lid

first you will want to route the wires for the sensor through the hole on the RH Side, and attach the sensor into the indent using the tab of double sided (foam) tape

I hooked up the CCS811 sensor as per the instructions from Adafruit

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
