Could you share your model for this? How well does it work? I've considered doing the same.

The set of laptops I'm willing to run non-macOS on is limited by the set of laptops that have physical touchpad buttons, and that's a diminishingly small market segment :(

They work quite well. The biggest difference is that they're attached to the same plane so the sides of the gap between them don't move up and down independently of each other, which makes it slightly harder to tell which side is which by touch. The pad can still sense your finger through them so it knows where you're clicking. I can post the model after I return from vacation next week, but you'll have to shape and size it for the target touchpad anyway. It's essentially just a flat rectangle with a radiused corner that's half the length of the touchpad, with a semi-circle in the middle to index my finger on. The thickness is 0.6mm for the tallest part. This will vary depending on the geometry of the bottom edge of your pad. I used silicone glue so it's easily removable with no surface damage.
