I took the opportunity to build this when I couldn't find a dock that would serve my exact needs, which were:

• Wide enough to hold Steam deck with Spigen Rugged Armor Protective case
• Ability to hold the USB hub without any strain on the cable (at either ends)

Just some extra information which might be useful.

• Steam deck's regular thickness in the middle is 18mm
• With Spigen Rugged Armor Protective case, that's increased to about 22mm
• This case has space for devices thickness upto 24mm

I've attached the Fusion 360 file which you can use to customize things like -

• increasing the size of the slot that holds the hub.
