We have an old Dell L100 keyboard that still works great with the exception of a broken stand clip. As you can see from my sketch, this was a rush job. I designed it in Tinkercad and it worked on the first try. I'm sure if I spent more time on it I could get it to snap in like the original part. However, the weight of the keyboard locks it in place just fine. I included the .gcode file, so those using PLA on an Ender 3 Pro (or similar) can just print it. I also included the rough sketch and broken part so you can determine if this will fit your keyboard.
