For all the enclosure design, I used the solids modeling package Autodesk Inventor. My son uses it in his engineering class - it is free to use for students, with full capability of the professional version. Go to their education site and you should also be able to get an educational copy. Or just use their free 30 day trial.
Inventor looks complicated but for the types of things I did, is relatively easy to use. I took classes at TechShop, a national DIY Makerspace. Maybe there is one near you. There appear to be lots of YouTube videos on its use otherwise. And there are lots of other 3D modeling packages out there as well.
I used a "Type A Machines" 3D printer, and used KISSlicer to generate the g-code.
