After 40 years of work and retiring, and seeing that I had plenty of free time, I discovered 3D printing I bought my first (for now) Bambulab A1 mini, simple to use, projects can be found online even if you don't know how to design, but I wanted to do more, following some tutorials I also learned to use Fusion 360 in a simple way, but every day I try to learn something and the results are visible now I have designed several useful things for my daily life now I have taken a step forward by starting to publish my projects We'll see how it turns out
