Print the first layers slowly, 5-10 mm/s and around 30-40 printspeed.
The button comes with 3 parts, 1 trigger and a left and right side of the button. You will need to insert a wire, prefareably a soft one to lead the connection to the trigger. I used solder and it works perfect, you could use copper wire aswell.
After glueing the 2 parts you need to cut a piece of aluminium of a soda can and fold it once. Cut it so it's around 2 mm wide and 3-4 mm in length, this piece is then inserted into the upper part of the button, together with some hot glue.
Once the glue has solidified you will need to now attach the trigger, also using hot glue and once that is done, bend it in such a fashion that it mimics the R2/R1 button of a PS4 controller.
Wrap the lower part of the trigger with some aluminium foil and you will need a soft material for the screenpart and the bakside of the button, I used those floorproection pads for furniture, but you could probably use something else, like rubber.
Remember that you need to cover the pad with aluminium foil, only the part that connects to the screen.
Sand the rough edges and paint it to make it look even nicer.
