I successfully printed the Modified Nintendo Switch Joy-con grip (remixed) by JopieLoempia but I found that the buttons would not hit the shoulder buttons on the Joy-cons.
I added approximately 3.5mm to the posts which allows them to fit into the Joy-con grip nicely but also allows for more travel.
Note: this file has been modified and exported at 96% (as suggested by the comments on the Modified Nintendo Switch Joy-con grip (remixed) file). I have also included a file set to 100%.
You may need some sanding to get this to fit but the post should fit perfectly!

I made the buttons larger to accommodate a longer travel
