Like me, if you occasionally do 3D modeling, or especially if you are creating 3D printing or industrial data, Autodesk Fusion 360 is an excellent solution. In fact, having used various tools for nearly 10 years, it seems there is no tool better than Fusion 360 for a lightweight design tool.
Fusion 360 is certainly a paid tool, but for personal users and hobby use, they issue a free license. (I remember it is renewed every year.)
The process is simple. First, go to the Autodesk Fusion 360 website, create an account, and log in.

Once logged in, scroll down to the bottom left, and you will find a download button for personal users.
It seems they also offer free benefits for startups and educational purposes, but if my memory is correct, it appears that you must fill out a separate application form to receive the benefits.
Since we are trying to obtain a personal hobby license, click that button.
Then, as shown below, it shows the difference between the free license and the paid license. I haven't been able to use the paid license yet, but I heard it has powerful features, so if you use it properly, you should consider purchasing the paid license.
Again, to emphasize, since we will be obtaining a personal hobby license, click the Free Get Started at the bottom.
Then, you will be asked to enter basic information to issue the license. Don't panic, as these are simple details, so let's register them one by one.
Then the download link for that user will be activated.
Simply download and use it. However, please note that the ID used to log in after installation must match the ID that activated the license, so be sure to check this before using it. Also, I recall that the license needs to be renewed every year. If you get confused, just run the steps above again.
