You try doing that with the modern thin keycaps you get these days!
This was my main thought when going through the process.
Also, I was lucky it was this end. I'm still not sure how I would've worked around the other end being broken.
I still should look into a proper replacement. This fix added a lot of metallic noise. It is noticeably louder than the other keys. Not like it really matters with this board anyway. Just added one more trumpet to the marching band I suppose.
