So, there's a few general ways I might tackle this.
The first is with a radius gauge. something like this set can be printed out. you can then just define the radius appropriately in F360, or whatever software you're using.
Then, in most CAD software- including in F360, you can insert pictures; and scale points on them so you can then build around it. because of optical issues with the camera this is perhaps not as precise as you might expect. However, it will get you close, and then you can print small cross sections of test pieces to verify and adjust.
Finally; the method I usually fall to: Just not caring to be perfect. You don't have to match the cradle perfectly to the contours. you just have to match critical points. take a ruler, find two points that can act as the 'base', and use that as the 'flat' surface, then find a another couple of points that keep it sliding off.
This is basiclly the answer. I like the third but especially. Personally, I would start with a profile gauge, since I don't think my PS5 has a very simple curve to it, scan it next to a metric ruler on a flatbed scanner, scale the ruler to be dimensionally accurate in fusion 360, iterate a few times and call it good enough.
I do kind of wonder about the design intent though. I don't know if newer PS5s are flat, butine isn't. I imagine the stand won't want to stay in one place very well. There are ways of solving this, but it will add extra complexity. Why not make a stand somewhere else?
that's why furniture usually has feet. :) some feet, some rubber dot thingies from amazon... problems solved. Profile guages are also helpful, yes. though one wonder's why it needs to be perfect? In some ways, that might actually make the stand harder to use. more finicky
If you're using feet you might as well just make a platform with posts, or lean into some kind of "C" like shape. The PS5, especially horizontally has a bunch of curves that are going to be very hard to match.
My idea is essentially to match the official stand that ships with it, but flip it and put a stand on the "bottom." I think it'll be really nice aesthetically but unfortunately it seems like it's not as simple as just mirroring it. To tell the truth, I'm probably going to end up going this route anyway, but I feel like I have to at least try the hard way first
