I would like to straighten the bottom side of the trackball, to reduce the casing size and move the trackball center point closer towards the shared wrist rest pad.

Has anyone done something like that before?

How much material can be cut away without damaging the internals and structural integrity too much?

Just the corners or some of the middle part as well?

Of course I intend to fill the hole with some hot glue or similar material to seal the internals.
