Ah ok. The AYUP/Garmin combo mount was a production item for a while, a couple of mates of mine bought them but I heard there were some problems with the mount snapping or something so he stopped making them. Or perhaps AYUP or Garmin told him he couldn't make them due to copyright or something?
There is another guy
Home - Raceware Direct - Custom Cycle Components based in the UK that does 3D printed Garmin mounts (not like this, more like the out-front mounts), maybe you could pitch your idea to him.
Edit: I see that he does a combined Garmin/GoPro mount already
