Cup holder

Most cupholders are designed to be attached to the vent ducts or slide into the window rubbers. But having a 4x4 you'll realize that these will only be fixed as far as the first major obstacle to conquer...
This design is very simple, holds the larger cups/bottles (like a bidon or your large milkshake) and most important... you can put three screws trought the bottom for a very rigid fix.
