There's OpenSCAD, but I don't think it's exactly what you mean

https://openscad.org/

For something this simple you can use OpenSCAD (https://openscad.org). It's free and pretty easy to learn. Below are the two commands required to produce the solid object indicated by the picture. The application can export anything you create as an STL.

Are you asking about something like https://openscad.org which allows you to code your model? An example of its use can be seen in the OpenFlexure project.

I use OpenSCAD. https://openscad.org - it's what the Thingiverse Customizer is based on (and if you upload .scad files to Thingiverse, the Customizer works for your design too).

One tool many people use for parametric modeling is OpenSCAD which is very utilitarian and has methods for constructing 3d and 2d geometry (and 3d from 2d such as extrusion).

OpenSCAD is free and open source. It's great for creating functional parts. Its input .scad files are just plain text files.

Download OpenSCAD from https://openscad.org and that NameTag.scad file from Thingiverse. Open the scad file in OpenSCAD, and use OpenScad’s text editor or Customizer view to replace ‘your name’ hit ‘Render’ then export to STL. Print the STL.

In the open source, cross platform, OpenSCAD, the following makes a regular tetrahedron:

You'll feel right at home with OpenSCAD ("The programmer's solid 3D CAD modeller)

Yea. Parametric is the right world. That would be very nice to have. Almost every single Parametric model (example) on Printables is on F360 (or the older ones in OpenSCAD - but they haven't done a new release in years now).

I am a total amateur here. But I found it natural to keep a relative spacial coherence in the schematic, and have it somewhat similar on the PCB side.

Though kicad would just dump everything randomly when moving to thr PCB view. As I understand, "packing" should help keeping this spacial grouping.

There is a plugin though[1] that does place the components on the PCB similar as they are placed on the schematic (and this does work with sub-sheet too). This is tremendously helpful starting point.

Alternative, the plugin SchematicPositionsToLayout.py attempts to group components on the PCB by the schematic. (I haven't used this one yet, but it looks promising.)

There's also a schematic position to PCB position plugin which does a good job of faking it, although whether it'll work nicely with that many components is debatable.
