My Logitech G19’s Enter key broke years ago, and the keyboard has been unused ever since. I always liked it, but never bothered to repair it — the broken plastic piece was lost, so I just stowed it away. Now, with a bit more modeling experience, I finally gave it a shot… and it works extremely well :) Hopefully this post motivates someone to try repairing their own broken electronics with 3D printing — or maybe someone out there needs exactly this key :)
