Drinking Straw Cap

This cap was designed to protect your straw and drink from contamination.

Straw cap hangs on top of straw when closed and opens to allow it to slide down the straw and provide access for drinking.


Keep insects such as bees out of your straw.
Avoid grubby passenger elbows rubbing up against your straw when drink is sitting in your car's center console cup holder. Nothing worse than skin crumbs and arm hairs in your drink.
Be sure to disinfect on a regular basis.
Should fit big fat fast food straws. If not, scale by 5 or 10 percent when printing.


Model has been provided in the open and closed position so you can choose which orientation you think will work best with your printer. Hinge should print in place with built-i tolerance of 0.4mm.

* if the tolerance is too large for your printer (hinge too loose or sloppy, let me know and I will create a version with a smaller tolerance.

Not for use by children. Can pose a choking hazard. Use only on cups that have a lid
