I'm lost in my own library #137
Description
Dave @rosenhauer
You have done incredibly beautiful work expanding and improving this library.
However, when generating simple project boxes I regularly run into problems.
There really need to be examples for generating “Shapes”.
Preferably both for the pre-defined shapes and examples showing how to create a custom shape.
The issue I am currently running into occurs in this program:
//-----------------------------------------------------------------------
// Yet Another Parameterized Projectbox generator

// This is a box for a handheldAerosolSensor
//
// Version 0.1.0 (2026-03-10)
//
// This design is parameterized based on the size of a PCB.
//
// For many/complex cutoutGrills, you might need to adjust
// the max number of elements in OpenSCAD:
//
// Preferences->Advanced->Turn off rendering at 250000 elements

if (true)

translate([56.8, 39.5 , 24])
{
rotate([0,0,180]) color("gray") import(myPcb);
}
}

The PCB should be positioned (approximately) 22 mm above the inside of the base.
Intuitively, standoffHeight should therefore also be 22. But when I do that, I get this:
The black bar is exactly 22 mm high and starts exactly at the top of basePlaneThickness.
Only when I set:
standoffHeight = 10.1;
do the standoffs appear to have the right height:
The pushbutton column is also much to long:
Only when I change p(9) of pushButtons from default to 22 does the height appear to be correct.
