I never did investigate using Pharo to building STL files.

But, I did used PharoJS to build a 3D scene using the three.js Javascript library.

The code is part of PharoJS examples

More about ThreeJS: https://threejs.org/

I'll be happy to help with it and discuss anything 3D printing. I am fond of 3D printing since I bought my first printer in 2017. You can find some of my prints https://nootrix.com/tag/3d-printing/

Cheers all

I am looking for classes which can be used to build 3D pictures. Spheres, Boxes, etc.

It is a fun thing for me to build, but on the other hand, if it is already done, I will use them.

Also, I am interested in 3D figures being outputtet in STL files. Is that done? It is an easier thing for me to build (have done some work already).

I want the stl format as I can pass that on to 3D printers. Are there anyone else who have worked from Pharo to 3D printing (prusa for example).

Best, Kasper
