Here is my attempt at a portable dock setup for the Valve Steam Deck. I don't have a deck yet, but as you can see from the pictures, I printed one to use for fit checks.

My goal was to make a small collapseable portable docking setup for propping the deck up when using it to watch videos and such on airplanes, or for at home to dock it for use on a bigger TV.

I designed this for use with the following port replicator: https://www.amazon.com/dp/B08SLS9W72 But really any of the same size with all ports on 1 side should work (amazon has a ton of them...) The cable is long enough to loop up and reach the USB-C port on the deck.

I used 5/16" wooden dowels cut to length for the hinges.

Since I don't have an actual Deck to test with, this is still a Work in Progress.
