A custom fit cup holder insert designed for 2018 Buick Regal TourX (Opel Insignia).
Specifically designed because the cup holder does a very poor job holding a liter sized “Nalgene” type bottle. Different stepped openings will hold just about any size drink.
Print in PETG for best sun resistance. Printed fully upright with tree supports.
