Accessibility has long been a concern for both game designers and hardware engineers. These considerations range from standard features like closed captions to colorblind modes and Microsoft’s unusual-looking adaptive controller for Xbox consoles.

One thing that Microsoft has yet to do is develop a system that allows one-handed players to use controllers effectively. However, a YouTuber named Akaki Kuumeri has a solution, creating a 3D printed tool that lets players use Xbox controllers with one hand.

Kuumeri’s design effectively migrates all of the controller’s buttons to one side without altering the controller itself. Users can configure the tool for the left or right hand, depending on their needs. He previously designed a similar attachment for PlayStation controllers, though the asymmetrical design of the Xbox One and Series X/S controllers added an extra layer of complexity. Kuumeri also put a significant amount of work into streamlining the setup and ensuring that the parts don’t interfere with each other’s movement.

In the left-handed configuration, a cluster of plastic levers move the A, B, X, and Y buttons to just above the directional pad, allowing players to reach them with their left thumb. A similar arrangement on the underside enables the player to access the right triggers with their left hand. Finally, users access the right thumbstick using a plastic arm resting on either a table or the player’s leg. They move the stick simply by turning their wrist and can press down on it with a spoon-shaped button that extends toward their left hand. The right-handed attachment is simpler, requiring only the trigger and leg pieces and a dish-shaped extension for the directional pad.

Despite the attachments’ complexity, it’s relatively simple to assemble. The left-handed version only has seven parts, while the right-handed version only has three. The 3D printed components snap together quickly and easily, and the device locks around Xbox One and Series X/S controllers with relative ease. While the Xbox version still ended up a little more complicated than the PlayStation design, the device still seems relatively easy to set up.

According to Kuumeri, he designed the PlayStation version mainly just to see if it was possible. He did not seem to expect it would be more than a curiosity but was amazed by the overwhelmingly positive response and was surprised by how many people his invention ended up helping. This inspired Kuumeri to develop a variant for Xbox One-style controllers and make improvements to the PlayStation design.
