Clamp-on desk USB cable holder (improved V2)

USB cable holder that will snugly clamp on the edge of a 19mm (3/4") thick desk without the need of fasteners.

This is version 2.
Improvements:
-Increased space between slots and made retaining fingers longer. Will reduce the tendency of USB cables falling out of the holder
-Reduced thickness of the bottom part of the clamp. Will reduce filament use and printing time (still takes more filament and time than first version because it is longer)
