I just wanted to share this because your flipper app is seriously so handy to have and figured this might be of some use to you maybe.

Obviously adding them all to the app would be totally insane, but you can use these to perhaps more easily find the info you might need to add requested key profiles to your app.
If you're able to translate the key cutter wheel profile dimensions to what they'll be IRL on the screen, then all you have to do is figure out the spacing and depths (which are also given) to make a usable outline. Just some food for thought, maybe you've already seen this, but I hope it's helpful in some way.
Thanks again!
