I recently bought a new 8BitDo Controller and wanted to be able to play some phone games with it while being on vacation but realized that there's basically no phone mounts for this controller yet.
The source model is a phone mount for an XBox-Controller, which I edited in Blender to fit around the 8BitDo Ultimate 2C Controller. It's not perfect yet and some parts can surely be optimized but it works as intended.
The only extra thing that's needed is some kind of rubber band that can be fit around the two parts to hold the phone inside it.

Oh and dont worry about the poor quality of my model in the photos. Because of little time, I had to print it on my older Ender 3 which made it warp quite a bit. If you print it, it should look a lot better. For the photos I used Black PETG from Anycubic.

To everybody having problems with this model: I don't use either BambuSlicer or a Bambulab Printer so I unfortunately can't help you, if there's problems opening it there with the Profile that someone else added. If you download the STL-File everything should work properly
