Description
This custom 3D-printed straw is designed for tall tumblers and features a clever air-channel notch at the bottom to prevent vacuum locking — no more fighting your drink when the straw seals up!
The straw is reusable, easy to clean, and fits snugly into most 20–30oz insulated tumblers.
Printed in PLA for testing, but PETG or food-safe filament is recommended for real use.
✔ No suction lock
✔ Slim but strong design
✔ Designed to be printed upright with a small support at the base
✔ Fits most common metal tumbler lids
