3D printing has become a hobby. It started a year ago with an entry-level model that I changed a lot. It was very instructive to adjust everything manually. In the long run, however, that was too much calibration for me before the fun started. That's why I've now bought a p1s. I also try to design objects myself from time to time. So far I have worked with Fusion 360, FreeCAD and Blender.
