Mug Dust Cover is a simple and practical lid designed to protect your drink from dust and debris while allowing airflow.

The model includes ventilation channels that help prevent condensation buildup, making it suitable for both hot and cold beverages. It loosely sits on top of the mug without sealing it, keeping your drink clean while still letting it breathe. The design is lightweight, easy to print, and works well for everyday use at home, in the office, or in a workshop. 

The project was done using build123d, so you can customize the parameters for yourself (GitHub repo link):

• mug_outer_diameter (default: depends on your mug) - Mug outside diameter in mm

• overhang (default: 3) - Cover overhang beyond the mug in mm

• top_thickness (default: 2) - Cover thickness in mm

• vent_count (default: 6) - Number of ventilation channels

• vent_width (default: 3) - Width of each ventilation channel in mm

• vent_height (default: 10) - Height of each ventilation channel in mm
