Serial Port I ETH2GC Gamecube ethernet broadband adapter with glued in clips

matsieee notes on their model that the clips are prone to breaking. Since we're gluing anyway, we may as well print the clip in its ideal orientation. Brilliant idea btw. Much cleaner solution than webhdx's eth2gc solution imo. Also some minor tweaks: I added a draft angle to the sides of the outer face to match the GameCube's trapezoidal opening as well as reduced the edge radius to match the profile of the GameCube case more closely.
