after opening the main 4 screws remove the side cover and lay it on a table
remove the screw but keep pressure and release slowly so the springs and ball bearing wont fly
i reused the original magnet in the model but in the modified one its flipped to fit in the height
i dont think that direction of the magnet have an effect but havent tested deeply.
mod at your own risk
