  Notes
    ! Prints TOP DOWN as exported — the hex pocket faces up, no supports, no bridges. The bed face becomes the knob's top.
    ! Push the hex in cold; if it fights, a drop of CA glue beats reaming the pocket loose.
    ! Thread the bolt through BEFORE seating the head — seated heads don't like to leave.
