SipShield - Universal Drink Cover with a Shutter

Keep wasps, flies and leaves OUT of your drink - and always know which
drink is yours.

SipShield is a universal drink cover for garden parties, BBQs, picnics and
camping. Concentric rings on the underside let the same lid sit securely on
almost anything: water glasses, wine glasses, mugs, beer steins, cans and
jars with rims from about 48 mm to 86 mm.

The straw hole is controlled by a PRINT-IN-PLACE swivel shutter that clicks
open and closed with a satisfying tactile detent - no assembly, no
hardware, it works straight off the print bed. Open it, drop in a straw,
and close the shutter against it. Glass unattended? Click it fully shut.

WHOSE DRINK IS THIS?

The set contains six lids numbered with dice-style pips (1-6) on the
shutter. Give every guest a number and nobody mixes up drinks again. With
an AMS you can also print each shutter in a different color (per-color part
files included).
