PS4 One-Handed Trigger Extender

This design is a trigger extender for the PS4's DualShock 4 controller. The purpose of this part is to make the controller more accessible for people with limb differences or other physical disabilities who may not be able to easily use the controller with two hands. The extender allows both triggers to be pressed while holding the controller with one hand. Both the SolidWorks and stl files are available for download.

After printing the part, there are two options for attaching it to the controller. First, the part can be glued directly to the trigger with hot glue or super glue. Second, a bolt can be used to clamp the triggeer extender to the trigger. This second method is detailed below.
