I have the P1S and there is a hole on the top right of the printer. Light leaks out of it and it was bothering me so I created a plug/button to go in there. I've included a blank button(stl) so you can ring it into bambu studio and add text on top if you like. I also included two Tron themed buttons as that goes with my overall theme for my P1S and AMS stands. Enjoy
