Need help with ideas on how to grind down the tiny ceramic feet. Without grinding down, the height interferes with mouse tracking when I turn the mouse sharply. Tried just sliding them repeatedly across some fine grit sand paper (P400) that my friend had. Any specific tool or sandpaper grit that I should use? Thank youPics of what I'm working with http://ift.tt/2pQLwVM via /r/DIY http://ift.tt/2q9POdT
