MOUNTABLE CUPHOLDER

I MADE THIS CUP HOLDER FOR A GUY AT WORK THAT HIS COFFE CUP WAS TOO BIG FOR HIS TRUCK CUPHOLDER. HE WANTS TO SCREW IT INTO HIS DASH AND THATS NOT MY IDEA OF THE BEST WAY BUT WHO KNOWS. MAYBE IT WILL WORK. DOUBTFUL BECAUSE I DIDNT MEASURE ANYTHING AND IT TOOK ME LIKE 5 MIN TO COME UP WITH THIS TERRIBLE SKETCHY DESIGN BUT HERE...NOW ITS YOURS IF YOU WANT IT
