Topeak Ride Case to Enve Aero Stem computer mount adapter

I needed a way to attach my iPhone with a Topeak Ride Case to my Enve Aero Stem computer mount, so I designed this adapter. 

I used a brass insert pressed in from the top.  A bolt from the underside secures it in place so it won't pull out. I've ridden a few thousand miles on it with no wear or loosening.

It should work with other computer mounts that have inserts for Garmin or Wahoo.
