The body of the rear plastic screw (that secures the daughter board to the marker) broke off from the head of the plastic screw, and is still in the threads (while the front thread hole is clear and is not compromised); it will need to be extracted if you want to utilize the rear thread hole, although the front thread hole provides enough force to keep the board in place. I'm limited to 24 photos in this listing, but I have many more to share with you if you are interested in the marker. I'm just a message away if you would like any of those photos, or if you have any questions.
