I designed a Modular Ergonomic Switch Grip. It wasn't printed yet, so this is all I had. The modular switch grip works in 2 ways, attached to the console and in controller mode. The grip portion of the design is made to be used on both the switch and the controller mode so it's fully modular and infinitely adaptable. There are 2 other pieces to the design, I call them Links. The first one (middle in the picture) is made to connect the two controllers for "controller mode" and the wide link is to stabilize the controllers and prevent them from falling out in handheld mode.
I made the Grips on the attachment to fit on both controller and handheld mode to both save material(it takes a lot less to print) and because having to connect a bunch of things is less convenient than connecting just a few modules.
I made the controllers angled because the buttons and the joystick lower down on the controllers were hard to press in its normal vertical position.
Reason why I made it modular is because that's what the switch is all about and I wasn't gonna let the modularity go away
