tracksyde, thanks for the video. PM me with an address if you are interested in a copy of the final design. You are on your own with the electronic parts though.

I wish I could take credit for the video, since that would mean I have my Model 3 . I just happened to see a video where a guy measured the pad and I happened to come across your post asking for the measurements so I replied. I should've been more clear.
Maybe you can find someone local to you to try it out on?
I definitely like what you're doing. Keep up the good work.
