So, over the weekend at Riptide I worked on this one controller (don't remember specifically what work was done) and the Z button fell out. I couldn't find it and assumed it was just a regular OEM Z button so that's what I put in. Well, come to find out after I had finished cleaning and packing up I found this Z (in the photos). I do remember that the resin button set was, it was an OEM color scheme and they were bald.
If anyone knows who this belongs to, please let me know! I will need a photo of the controller so I can confirm, of course, and shipping will be covered by me (I'll make sure to include the necessary screwdriver so you can open your controller).
Please spread the word, just want to find the owner, it was an honest mistake.
