My doorbell still worked just fine but the button destroyed itself. I didn't want to bother installing a new one right now so I decided to print a replacement for the button. I found nothing else like this on Thingiverse so I figured I'd share for anyone else who doesn't want to take the time to design one themselves(which literally took 2 minutes). This replacement fit with a little finagling over the remnants of the existing button, if the spring and metal actuator are still present you should be able to do just as I did and just push the metal actuator into the recess in this replacement button and then push it back into place in the doorbell itself.
