Rescaling usually doesn't work well because the MagSafe portion is static between all sizes. Hence, every custom sizing needs a custom re-design.

In theory, with parametric design (eg OpenSCAD, Autodesk Inventor, etc) a model could allow you to enter the phone dimensions and it automatically re-calculates the correct geometry.

In practice, experience says doing this (in a robust way) is a lot harder than it sounds. ;)

Thanks, very nice design and write-up.

It's not really that much harder, as long as you know which dimensions you want to be variable from the start. Going back and changing everything after the fact is a massive pain.

I’ve started to put something together in OpenSCAD: https://u.ale.sh/braunscadv1.png

I’ll share the source once it’s a bit less painful to look at (right now everything is a bunch of copy-pasted spaghetti code :')

I am extremely interested in this. I’ve got a new iPhone 16 and I’d love to use it in its case with this stand.

I wonder if there's a version that's more of a shelf so could accommodate (m)any sized phones and with/without cases?

I think it's doable with a parametric design in Fusion but it is definitely more work up-front or re-work after you have a working version. Getting a well parameterized and set of constrained sketches can be a time consuming process since I don't do it every day. It's probably the part I've struggled with the most in making 3D printable designs (I'm not OP but design cosplay props for my kids) since I don't always know what I want the final dimensions to be.

And a parametric design requires you to buy the commercial Fusion license.

No it doesn't, unless you mean some more advanced parametric features that just the basic parameter driven modelling.
