I have another generic one, but it's trivial to 3D print your own. However, I found that it didn't actually inform how I would like the key when used in anger.

I have another generic one, but it's trivial to 3D print your own. However, I found that it didn't actually inform how I would like the key when used in anger. Only actually using it in a keyboard would do that. So far I'm using three different (non-Cherry) MX keys: lightest and linear for the weakest fingers which are typically modifiers, heaviest for the center row strong fingers.
