This is a cupholder adapter for using a huge water bottle (64 Oz.) in your car. For a smaller cupholder adapter, please see my other design here. This was specifically made for a Dodge Charger, but it will fit any cupholder with a 74mm diameter. This base is 74mm wide and 65mm tall before widening out to accommodate 123mm wide bottles at 85mm height. The base is also hollow to prevent vacuum suction and can also hold 70mm wide bottles/cups as show in the pictures (medium takeout cup).

There is both a centered and offset profile. If your car's cupholder are close together, the offset is likely better to be able to use the other one in your car.

The water bottle pictured is a RTIC 64 Oz. water bottle
