Modification of Pixel 5 Power button by eldpollard :

• Update length of the ‘pin’ pressing the contact
• Update height of the button
• Add ‘clip’ at the base to lock into the slot of the phone

Print height of the clips might be too high for the printer tolerance, a small amount can be chipped off with a cutter or sanded to ensure enough clearance (if when inserted the button stay pressed, remove it and remove some height to the clips).
