Window Screen Corner (Smaller)
After trying a couple other window screen corners on here, I found that they were either too big or didn't align well when scaled to fit. So I created my own version. Notice how the bracket has room for the thickness of the aluminum on both sides. Also, I made sure the gap would allow for the window channel alignment and space for routing the screen tubbing. The aluminum part this fit for me was about 8.5mmx19.3mm.
