Generating STL file from KiCad
Making a projectbox with all the holes in the right place is quite a challenge.
Luckily for the makers that use KiCad
as a PCB making tool there is a rescue!
Tools needed
If not already done you first have to install the latest version of FreeCAD.
Then you have to install the KiCadStepUp
tool with the Addon Manager
.

Creating a STEP file with KiCad
Start the PCB Editor

From the File
menu select Export -> STEP

In the popUp [Browse]
to the map where you want to save the STEP file and click on [Export]
.

Start FreeCAD

Click on the select box ..

.. and select the KiCadStepUp
tool

Go to File->Open
and select the STEP file from the KiCad Export

.. and click on [Open]

After a while you see the result of this import

Now all you have to do is Export
this file

Select "STL Mesh
" as type ..

.. and click on [Save]
The result is a nice STL file

Use this STL file with the YAPPgenerator
Add the following code to the beginning of your .scad
file:
myPcb = "./STL/DSMRloggerESP32_PCB.stl";
if (true)
{
translate([42,43,4.6])
{
rotate([0,0,90]) color("darkgray") import(myPcb);
}
}
myPcb
has to point to the generated .stl
file
With translate()
and rotate()
you can place the .stl
file to the exact location of your projectbox. This is a bit fiddling in the beginning but once set it does not change anymore.
