Interesting, thanks for sharing! Doing a quick search, I found the 3 pods for sale on Ebay
HERE for less than $15. But it lacks the right escutcheon plate.
Of the same family of products, I purchased a 2 pod panel from Ebay
HERE for less than $9 and used the outlets as shown on my older E350 interior design, installing them into the front of our center console. Power to them is seen as the short length of vertical gray cable below the radio. I have a connector in back so a mechanic can unplug and remove the center console.

Our older console design has a problem with the 12V outlets placed just to the right of the gear shift lever. The power cords we plugged into them, stuck out so much that they badly interfered with shifting gears up & down while driving in the mountains & canyons. Also, the power cords laid across the center console to the passenger seat which was messy and interfered when using the cup holders.
The two new outlets (one 12V & dual USB) resolved all that. Electronics getting charged are placed in the lower bin so the cords to them don't interfere with anything, and the cords to the passenger stay off the center console. This has worked out exceptionally well for us. Now the original 2 outlets by the shift lever don't get used at all which is great for the driver.
