This headphone stand clips onto a 2010 Mac to keep headphones off of your desk and out of the way. It also includes a forward facing headphone extender and USB hub so you no longer need to reach behind the computer to plug anything in. The whole piece clips into the vent on the back of the computer, and is quite sturdy. I also printed out RobertHunt's enhanced iPhone dock (http://www.thingiverse.com/thing:6931), and glued it to the top of the mount with a little bit of CA glue.Print the headphone stand with support. Large layers are fine, because the part is already stronger than it needs to be, and there is no fine detail. Remove the support and test fit the part. Cut away any excess material from the print that prevents the part from fitting properly. Insert the USB hub (Belkin 4 port hub) and female end of the headphone extender in their respective slots, and apply a little bit of CA glue to keep them from slipping when you plug or unplug devices.Print RobertHunt's enhanced iPhone dock (http://www.thingiverse.com/thing:6931) which I have included as one of the files, and glue it to the top of the stand. Remember to instal the cord before you glue it, because once its glued its sealed in. You should also make sure the cord isn't backwards or broken.
