Summary

I wanted to use my PS4 controller on my PC, but most games are designed to show Xbox button prompts. So the only logical solution was to change out my PS4 buttons.

Instructions

Buy the plastic for molding. I purchased some clear molding plastic from Tapplastics. You can find it here -> http://tinyurl.com/blwpq8r (Also don't forget to purchase the catalyst for this product if you choose to use it)
Using a 3D printer, print out the lettered buttons and a Button_Mold for each.

Optional step: Treat the printed parts with acetone. I recommend pretreating the molds so that you will achieve a smooth button as an end result. I have found that a acetone vapor chamber can produce these effects quit nicely. It is simple to do, but if you have never done it there is a quick tutorial over here -> http://youtu.be/Xj53P2YzYGM

Mix up some resin and pour just enough into each mold so that it covers up the top half of the button.
- I've heard that pretreating the mold with automotive wax may help prevent the resin from sticking to the mold, but I didn't have the chance to try it
Once the parts are cured break open the molds and you are done.
- If the surface of the button is still a little tacky, you can either put them in a warm spot and let them cure longer, or you can add an acrylic clearcoat
