pyscad VS SolidPython

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).

https://github.com/SolidCode/SolidPython --- apparently there's a fork as a v2 which is to be preferred

Then use SolidPython to generate the scad files. ;)

I wonder how many OpenSCAD wrappers now exist? I know of scad-clj [0], openpyscad [1], and solidpython [2].

I particularly like scad-clj, because of `lein auto generate`. It watches source files, and regenerates the OpenSCAD files automatically, which OpenSCAD then also picks up. Although I'm not well versed in Clojure, and find debugging Clojure tricky, the workflow is just so good.

Check out SolidPython, a front-end to OpenSCAD in Python that generates OpenSCAD code. It's actively developed (latest commit was 16 days ago) and has some excellent features, including first-class negative spaces - once you declare something to be a hole, the library makes sure that, no matter what, you will get a hole in the final model.

The mesh is already generated. I'm using a library (https://github.com/SolidCode/SolidPython) that generates OpenSCAD code which can be exported to pretty much any 3D format you want.

If you share an Excel (or, better yet, CSV) file, I can put up some Python code that outputs the OpenSCAD you want. I wrote SolidPython for exactly situations like this-- when you want to interface with other kinds of programs than just modeling.

In addition to first-class negative space (a hole like OP asked for), the SolidPython OpenSCAD binding also includes +, -, and * operators for union, difference, and intersection. (Disclosure; I’m the author)

Also, if it’s screw threads you’re after, there may just be some faster (== non-minkowski) ways to do that. OpenSCAD calculates polyhedrons much faster than big unions of parts. Buut, OpenSCAD also kinda sucks for doing vector math. I wrote SolidPython to get around some of the constrictions of OpenSCAD, and the screw_thread utility method should render decently detailed threads (120 segments per revolution, say) in a few seconds.
