I have a Lego M motor that is broken. I'm following the instructions here to try to fix it but the little tabs that hold the plastic frame together just won't budge no matter how hard I'm pushing them (4:20 in the video).
Does anyone have any suggestions as to how to take this thing apart? I'm deforming the plastic on the tabs since I'm pushing so hard with a screwdriver with a star head on the end and they look terrible now.
