This fits in the bin between the rear seats and is secured by the nut that secures the lower seat squab to the car. To install:
Cup holder is at 4 degree angle so that the holder sits level with the ground. Diameter of the cupholder is 80mm, large enough for standard Hydro Flask w/rubber bottoms but not the wide models. Optional spring insert for narrower diameter cups (TPU preferred), insert ring side down.
Cupholder liner is optional and should be printed in TPU or some other flex material.
