About the Controller Attachments
How the controller attachments work, and how they're made
Snap-on Technology
Akaki One-Handed Attachments attach themselves on regular gamepad controllers with a satisfying snap, forming a solid connection. Removing the attachment is just as easy.
Mechanism
The attachments are purely mechanical − no electronics or batteries. Moving linkages and arms manipulate the buttons and thumbstick, making them accessible with just one hand.
Optimized for 3D printers
The plastic parts are produced with a 3D printer. The design is optimized for the printing process. If you look closely, you can see many details that are specifically designed to allow the printer to print the pieces without support material, and to reduce post-processing.
