This is a 3D-printed replacement for the original silicone trigger dampers in Xbox controllers. Simply attach them to the original position using double-sided tape or glue. For optimal feel, it is recommended to print them with TPU material of 95A hardness or less.
The set includes:

• Return-stop damper (the smaller one) for the initial press.
• Full-travel dampers in two thicknesses. Both work perfectly, with the thicker option providing more cushioning.
