Car Cup Holder Expander (Sizes: S / M / L)

You finally got a massive tumbler or coffee thermos, but it refuses to fit in your vehicle console. This adapter solves the problem by bridging the gap between standard vehicle inserts and oversized drinkware. The base section remains a constant diameter to sit firmly into most standard consoles, while the upper receiver accommodates wider bases and features a deep cutout slot so your mug handle rests perfectly without tilting or spilling your coffee during a commute.

Providing options is crucial because not every bottle is the exact same diameter. I included three different upper receiver sizes small medium and large so you can pick the exact one that matches your specific travel bottle. Since the bottom peg stays the exact same dimension across all versions, you only need to choose the top profile that hugs your drink best. I highly recommend printing this in PETG or ABS or ASA since PLA will warp and melt in a hot vehicle interior during the summer.
