This Model has a ball bearing. Credit to Jerryie and pixel 2.

Instructions:

1. Snap brace into the back of the frame. Bending the brace will make it easier.
2. Snap the rack into the pivot. The indent on the pivot goes up. Work it back and forth for 30 seconds to smooth out the ridges of the print.
3. Glue the top and bottom edge of the bearing into the frame. Wait for glue to dry. Superglue might leave a white haze on the controller if it's not dry. *sometimes not necessary
4. Snap the rack onto the frame.
5. Pop the frame on the controller. Go from back to front. The tab on the front needs to key into the USB port.
6. Slide the pivot down on the stick. The ball joint should be in the center. Align the bottom edge of the pivot so it's parallel with the rack. The stick should return to the neutral position when pushed to either extreme.
7. Center the wheel on the rack and press it into the bearing.

The brace is the 2nd to biggest peice. The pivot is the part that goes on the controller stick.
