Simple cell phone holder to insert in the CD tray of your car.It is based on the original work from http://www.thingiverse.com/thing:644402, but redesigned in OpenSCAD to make it parametric so it can be used for any smart-phone.The measures in the script and the STL are for my Google Nexus 4.Don't print this in PLA, as it will bend when your car stays in the sun! ColorFabb XT or ABS will work fine.
