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

Straw cap hangs on top of straw. simply lift and guide top of straw through side hole and slide down the straw to 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.

This cap is is solid state (has no moving parts) unlike my other one that has a hinge,

Should print with no supports.

Not for use by children. Can pose a choking hazard. Use only on cups that have a lid such as fast food cups or else the cap may slide into your drink. Use at your own risk.
