ABXY buttons for Dualshock 4 controller!
I use DS4 controllers on PC and me and my wife play from time to time together. She has trouble remembering button layout sometimes, so this is perfect solution.
You can make sphere on top of buttons with “Top Coat” for nails (I took some from my wife) and cure it with UV lamp. It will then be perfectly smooth and it will feel like original.
You can follow this tutorial for disassembly:

You will need 5 colors, if you have AMS, I made trick with filametn switching.
More info is on printing profile description.
Have fun :)
