• Cost-Effectiveness: Build powerful automation systems without breaking the bank.
• Local Control: Keep your data private by running everything locally.

What You'll Need

Before diving into the integration, gather the following:

• ESP32 Dev Kit: The microcontroller you'll be programming.
• Home Assistant: Installed and running on a Raspberry Pi, PC, or server.

So, in this blog, I'm going to show you how you can make your first 3D-printed case for ESP32 for Home Assistance.

3D Model Development:

First, we need a better 3D print case for our project and that should contain lots or holes to get better air ventilation.

Here is my 3D mode, I have referred to this design from Thingiverse and this is one of the simple and good case with better airflow.

As you can see here there are lots of airflow vents.

Next, we need to print our model but the issue is as a beginner, I'm not sure about print settings and other parameters. So, I just used JUSTWAY, you may have heard the same name PCBWAY. But JUSTWAY is service provider an the are providing all the hardware prints like 3D and CNS.
