Donkey / Buffalo handle Trust Disk-Left

This is a part of the Bugaboo Donkey / Buffalo handle lock system.  I call it a thrust disk as it moves the handle locking cog inward to unlock the handle.  It is moved by a three fingered (Actuator) pushing on the ramps of the disk as it's pulled by a cable attached to the release button.  I also have 3D print versions of the actuator and release button.
NOTE BUGABOO DENOTE LEFT AND RIGHT FROM THE FRONT OF THE STROLLER WITH THE SEAT FACING FORWARD.  Most parts will have an L or R stamped on them usually as part of a serial number.
