The controller handle fits well in the hand and the Joy-Con fits perfectly in the designated holder. It does not wobble and can simply be pushed out from below after use. The grip is ideal for playing games like Mario Kart with friends, where two controllers are needed, because the otherwise awkward, small Joy-Cons feel like a standard controller. Thus, they offer a simple alternative to the Nintendo Switch Pro controllers, for example, which are comparatively very expensive. The holder fits both the Joy-Cons of the standard version of the Nintendo Switch and the Oled version. The dimensions of the object are 85mm x 135mm. I have printed the controller with the Elegoo Mars 3. I printed the controller solid, placed it upright and supported it so that it could be printed in one piece.
