Cigarette Humidifier / Quick-Print Ventilated Tube

Description:

A compact and functional cigarette humidifier shell, designed to prevent cigarettes from drying out while stored in a box or case.

The internal space allows you to place a wick made of tissue paper, which gradually releases moisture through the elliptical vents on both sides of the tube.

This smooth, hollow tube prints in under 6 minutes on a Creality Ender-3 (at 0.2 mm layer height).

Its minimalist, vented structure promotes gentle airflow while maintaining excellent mechanical strength for its size.

How to use:
