Having been one of the thousands who got ripped off on a Kickstarter for a Mobile Amazon Echo (Voder - The Next Thing Co.), I decided to make my own. This is a remix from my original Echo Dot stand I designed a couple years ago.
Now using this, my Mazda 5 now has a full size ECHO ECHo ECho Echo echo in it.
This is designed as a clean and easy print, though some printers might have an issue with fine points at the top. If you experience this, I would recommend just cutting off the top 2 mm post printing.
