My buddies dog ate his L1 button out of his PS4 Controller and this is what I came up as a replacement.

Highly recommend printing in the orientation I've got them in even though it'll require lots of supports because otherwise some of the smaller portions may be too weak. Lots of post processing is required to get a good fit with a smooth button action. Mostly centered around to two middle guide posts which slide in the channel to guide the button on. Had to do a lot of work with my file to get it just right but I did 3 of them and they were all fine after enough cleanup.
