For anyone wary of running random commands that you don't recognize what they're doing
Navigating the Linux shell would but much easier if you learned a bit of BASH. Essentially every Linux distro uses BASH for its shell commands, some commands such as cp (copy file/folder), mv (move file/folder), cd (change active directory/folder), rm (remove file/folder), mkdir (make directory/folder) will be on every Linux distro you use, the only time you get new commands is when you install packages that give you new commands, so a command such as fastfetch wont be available to you until you install the fastfetch package.
Hope this helps!

I would suggest reviewing the CAD files for the Steam Frame, if you never used CAD software before you can take measurements from the 3D model. I would suggest FreeCAD but you may need to tinker a bit to get it working, but at least this way you can start working on a solution.
