One-Handed Controller Modification for PS4

This inexpensive, 3D-printed PS4 controller modification will allow for the user to operate their DualShock 4 controller with one hand. This controller modification snaps onto your existing PlayStation 4 controller and allows you to use either your left or right hand to use both joysticks and access all of the main buttons.

This design was created by Akaki as part of the The Controller Project.

This controller adaptation allows users to operate their PS4 controller with only one hand. The PS4 DualShock 4 controller is symmetrical, so this controller can be printed for either hand by mirroring the parts using your 3D printer slicer.

For a left-handed controller setup, the right joystick is operated by moving the whole controller. By moving the controller, the 3D printed parts enable the joystick to move simultaneously. In addition, the right shoulder buttons are migrated to the left side so all four shoulder buttons can be used with the index finger. Similarly, four 3D printed arms are used to allow the user to press the square, triangle, circle, and X buttons from the left side.

On the right handed version, the controller modification works the same way, except the four arms will alternatively be used to press down on the four arrow keys.

There are two different attachments for the bottom of the controller shown below that can be used depending on whether the user chooses to strap the controller to their leg (right), or can rest it on their lap or a surface of their choice (left).

If you want to see how it works, you can watch this video to see the controller modification in action.

This controller adaptation makes it easier for someone who may have a difficult time holding and using a controller with both hands, or has greater dexterity with one hand than the other.

This is a beginner level build that involves 3D printing and assembly.
