After rooting my Ender 3 v3 KE, I found I prefer the Guppy UI for the Nebula pad. But that turns the screen to a landscape orientation. I created this mount so that the pad can be mounted landscape and also add a mount for the Nebula camera. 

I have included the file from Fusion360 so you can use it to remix this mount if you'd like. I only have the KE, but from what I understand, this will work for the SE as well. 

I printed it with 3 walls, 20% infill (gyroid) using PLA. I think this is likely overkill, but I tend to break things. 

Tag me in your makes and if you remix, let me know how it goes!! I'll be looking to update it if I notice anything I don't like about it…that said, share with me what you do and don't like so I can include it in any future updates!
