I got into 3D printing and CAD around 2018 with my first Prusa i3 MK3. That workhorse printer went to a good home (donated to local library) when I bought my MK4 in early 2024, and then subsequently converted it to a Core One in early 2025.
Much of my early design work was done with OpenSCAD, but now I do almost everything in FreeCAD.
