Mouthwash Station

A compact and practical mouthwash cup system designed for individuals, couples and families.

Each reusable cup holds approximately 25 ml. Since many mouthwashes recommend using 20 ml per rinse, the cups provide a convenient portion with enough space to prevent spills.

The download includes holder versions for:

• 1 cup

• 2 cups

• 3 cups

• 4 cups

The cups are stored upside down. Each position has an open drainage hole that allows residual water or mouthwash to drain away while improving airflow around the cup.

The holders can be placed on a bathroom countertop or attached to a clean wall using suitable double-sided adhesive.

I printed the set in two colors using PETG, but it can also be printed:

• in a single color;

• with contrasting horizontal stripes;

• with a different color for every user;

• with a different number of stripes to make each cup easy to identify.

Recommended print settings:

• Material: PETG recommended for bathroom use

• Nozzle: 0.4 mm

• Layer height: 0.18–0.20 mm

• Walls: 3

• Infill: approximately 10%

• Supports: not required

Print the cups upright and the holders flat on the build plate. Color changes can be made with an AMS/MMU system or with manual filament changes at selected layers.

Please choose a filament suitable for your intended use and follow the filament manufacturer’s safety recommendations. FDM prints are not automatically certified as food-safe.
