Without even knowing Steam was making a dock for the Steam Deck, I went looking for one and was pretty disappointed in what I was coming up with. So naturally, I took the best ideas, combined them and made my own!

Introducing the SteamDock! The best dock/port replicator you can 3D print yourself for your Steam Deck!

There are a lot of copycats out there, but this is the original as mentioned by TechRadar:

The SteamDock will add the following to your Steam Deck:

1) HDMI port
2) USB 3.0 ports
1) SD/SDHC port for additional storage capacity while docked.
1) USB-C port with 100w charge pass-through
1) Gigabit Ethernet connection

If you have or want a dBrand skin on your Steam Deck, it will still fit just fine in the SteamDock.

Official Valve dock? What a piece of crap! Print yourself up a SteamDock and give your Steam Deck the functionality and stability it deserves! And tell all those copy-cats out there to suck it!

Edit 1: Updated the .STL files to clean up a few minor blemishes some folks pointed out. Absolutely nothing that affects functionality, just extremely small points that aren't even visible on the final print but can be seen when zoomed in with your slicer. Also made a minor change to the opening for the SD card for a smoother print on some printers.
