After my previous Instructable, I wanted to make a dock that was more widely manufacturable, and was capable of actually charging the unit while docked.
This dock is made from thin wood (lauan, .140" thick) and one small piece of 1/2" wood. Although I used my CNC Zenbot machine to cut the parts, the parts could easily be made using a dremel or even an exacto, with the lauan wood or maybe even some chipboard or cardboard.
It uses some readily available spring pins to provide the connection points for the charging. Currently, it does not activate the 'dock' mode, mainly because it appears to require a complicated information transfer with the third pin. When smarter people than me figure out how to activate the dock mode with the third pin, I'll be sure to attempt to include it in this design.

I'm sure there are a lot of variations that are possible here, but I will list what I specifically used.
Materials:
Approximately letter sized sheet of lauan wood, approx .140" thick (1/8"-3/16")
(Alternate materials are definitely possible, and I'll discuss what to do if the thickness is different)
3" long stick of 1/2" x 1/2" wood
(Again, this can be changed, but the material needs to hold the connection pins snug)
2 connector pins PRT-09174 from sparkfun
USB cord (or other 5V <1000mA source wiring)
Tools:
Tool to cut the wood: either exacto, coping saw, scroll saw, or CNC router
3/64" Drill bit
Wire stripper (optional, or an exacto and band-aids)
Solder gun and soldier
