K1 - Chốt giữ bushing ray trục X (X axis rail bushing retainer)

I designed this part because the bushing was loose after removing the 2 springs at the top of the toolhead and the 2 m3 screws at each end did not secure it tightly. 

To install, just unscrew either the left or right m3 screw holding the bushing in place and sandwich this part in between and screw it back. Make sur to align the knob where the bushing is.
