HIGHLY IMPROVED Single Joycon Holder

So the original design (source Manabun) is a really incredibly useful design, but it has a serious flaw I was able to easily fix. There isn't a locking mechanism in the original, so any lateral force pops the joycon out of place and the SR/SL buttons on top don't line up and thus don't function. I added a slot for the joycon lock and a hole for your finger to depress the button on the controller to remove it. The button extension on the upper buttons are not modified, but I would recommend slowing down your printer for the buttons so things like ghosting don't impact the functionality of the buttons.
The files where the controller prints in two halves next to each other prints faster and uses less material than the whole controller printed as one piece. I removed excess material to reduce weight and material use, so the design is just as strong as the original, but places where there doesn't need to be a solid piece are cut away.
