Subject: enlarge holes on motor mount
X-Git-Url: http://challenge-bot.com/repos/?p=challenge-bot;a=commitdiff_plain;h=bedc9f60c886972ba9ddcc52e64c59491d7cbd3a

enlarge holes on motor mount

the screw and nuts will take care of holding the motor tight,
  so the holes can be big enough for the screws to slip in.
