Audi A3 8V Phone Holder Holder

No, that's not a typo in the name, it's a holder for my existing Belkin clip on phone holder. There are several Audi phone mounts on Thingiverse that go between the vents like this one however most required some additional item attached to the phone (e.g., magnetic mounts). I already had the Belkin clip on universal mount which is designed to slide into vents however this did not work in my car as the vent fins were too thin. So I modelled this version with its own fins sized exactly as needed for the Belkin phone holder. If you have a similar holder it might fit into this one. The inner diameter of the hole is 23mm, the collar has a 12mm recess before the fins start. The STEP file is provided for those that want to modify the design. I printed in ASA for heat resistance, ABS would also be fine but PLA and other less heat resistant filaments should not be used.
