I drilled out the 3 rivets that hold the slide in. Dropped the side of the drawer down and slid it open. Removed the organizer and riveted the slide back in. Good as new... because it was just assembled an hour ago.
I just came across this thread. We just got my boy a Vulcan cart. The drawer isn't opening because the organization grid is jammed up from being flipped over. I stuck my phone in there and took a video to confirm. Now to figure out how to free it up.
