Nexus One Dock

I've seen a lot of discussion about paper clip and cardboard docks for the Nexus One.  Thought I would post what I made the other day and applicable files I used.

This process could be applied for any phone.

This dock does not yet have a power source or a docking 'sense' capability, but I hope to add some of this in the future.  And of course, I would like to produce a version that can take my phone with the protective case.

This part was made using a CNC router mill, the Zenbot.

Step 1 Measure the phone

First effort overall will be to get a version of the phone into the computer where it can drive machining instructions.

Lacking a 3-D scanner, I have instead used a orthogonal cross section method to get close to the shape of the bottom of the phone.

Basically, I traced around the phone from the front and the side.  Using a 2D cad software, I inserted the picture and traced the line.  Now using a second 3D cad software, I place these two lines at 90° to each other.  Now, I have the framework to create a surface for the phone.
