Jump on the left platforms to get the middle Tripper on screen, luring it to the right. Get on the middle Tripper and use it to jump to the item. This requires a somewhat precise shot and jump, particularly if the top Tripper is in the way. The jump and shot can be easier and done at the apex of a single jump starting with a crouch. Freezing the Trippers can make this much easier.
