Node 202 graphics card support / brace

It's great that they included a support / brace for the graphics card in the Node 202 case but as it turns out, it doesn't work with every card. My Asus Strix 1070 is a bit too wide and their support piece can't slide that far out. And the card is heavy, the amount it sags scared me so I figured I'd print something that fit better.

While I was at it I'd figured I'd also remove the need to screw in the supports which required you to remove the bottom-part of the case which is a major pain.
