This is a model of car holder for a Nexus 5. It is designed to attach to a mount sold by Samsung meant for the Infuse. I simply removed the clip for the old phone and attached the new one. I used VHB tape. There is enough surface area that it should be able attach it to most mounts out there. This is similar to a project by Scroll http://www.thingiverse.com/thing:200073 That project was for a phone in a case and is meant to attach directly to the dashboard. This project assumes no case and some sort of mount. I have included STL and SW 2010 files for the holder and a rough version of the Nexus 5. DO NOT trust the Nexus 5 model. I was in a hurry and All I cared about was the bounds. I printed mine on a Replicator .2mm 10%
