Thank you so much for posting this video. After watching this I got mine apart today by sawing off the top (furthest from the table top) with a thin-bladed coping saw. Went quickly, but I almost sawed into the white battery box and nearly broke the electrical contact wires. There’s some robust plastic pillars inside supporting the battery box that I eventually had to snap with a screwdriver to get the “lid” completely off.
Is the battery box glued at the pegs or all around. Does scoring just cut into the glue and loosen it that way or was it molded one piece? I was thinking about giving it a try on my old one. I was trying to score it around the bottom of the box but I stopped to ask you first. Thanks.
