Straw Keeper for Stanley and Other 30oz Tumblers

Lift your straw to make sipping easier!

Early models of the Stanley Quencher 30oz tumbler let the straw slide freely, which makes it difficult to drink when the bottom of the straw is resting on the bottom. 

This tight-fitting ring fits around the straw of any 9.5mm straw, and can be easily scaled to fit other straw sizes.

This is a very fast <5 min print, and is a great way to finish off the last bit of filament from your spool.
