Can you clarify what the problem is that this solves? Your charging cable wiggles too much when it is plugged into the top? If so, I don’t appear to have that issue at least that I’ve noticed.

Yeah I have the Killswitch from Dbrand. It’s a great case and the travel cover makes the deck borderline indestructible. It is a bit pricey though at $75 but that also includes a kickstand (with built in microSD storage) and a skin of your choice. https://dbrand.com/shop/grip/steam-deck-cases
