My phone holder which clips to my car vent broke. This was an adapter I made to allow it to be anchored to the car using my CD slot. Although it was just made in PLA it seems to do the job very well. The slot matches my phone holder's broken piece very well. The curve in the part that goes in the CD slot makes it very stable. The thickness seems to be very good for my phone weight. It was mostly created in TinkerCAD.
