How do you model complex curves? ( kbin.run )

Can someone explain or point me towards a good tutorial that explains how to match complex curves, like the PS5 side panels?

I want to make a controller stand that sits on top of my PS5 in it's horizontal position.

I'm most familiar (but still very beginner) with Fusion 360, but I'm open to trying other software if there's some killer feature that makes this easier.

Any tips appreciated, thanks.

3D-scanning and work with the digital twin.

OpenScan is a opensource project for smaller objects. With the PS5 maybe a Creality CR-Scan but it's quality will be borderline unusable for a shape like a PS5 panel. So after all the entry scanner for a job like this could be a Shining Einstar.

Good news: If you own an iPhone try it's lidar first. Creality CR-Scan is only slightly better than iPhones. With Android phone, you could try photogrammetry but to scan the PS5 part you would need matting spray and even more tracker (small dots glued to the surface).

Btw. Somebody somewhere at some point in time already scanned or modeled the PS5 side panel. As starting point check GrabCAD and thingiverse for a 3D-model.

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.
