Car Cup Holder Expander for Stanley & Large Tumblers

Keep your large tumbler secure and stable with our 3D-printed Car Cup Holder Expander.

Designed to fit larger cups and tumblers in standard vehicle cup holders, this adapter provides a wider and more supportive base for everyday use on the road.

The design includes three different base sizes — 65 mm, 67 mm, and 69 mm — helping it fit a wide range of common car cup holders.

It is especially useful for large tumblers such as Stanley-style cups that may be too wide for standard vehicle cup holders.
