Does your kid treat hand-washing like a chore? Make them laugh instead! This is a minimalist, low-profile 3D attachment designed specifically for automatic foaming soap dispensers with a small cylindrical 5.35mm exit tube (approx. 20mm diameter face). I designed it specifically for this dispenser https://s.click.aliexpress.com/e/_c3fiKcTt or on amazon https://amzn.to/3R7UY7N but it might work with others.
 

Why it’s great:

• Kid-Friendly: Turns hand-washing into a fun moment as the soap "vomits" out of the character's mouth.
• Simple & Fast: A flat, 2D-style design that prints in minutes and requires zero supports.

Print Settings:

• Material: Recommended in PETG for better water/soap resistance, though PLA works too
• Infill: 15-20%.
• Mounting: Designed to friction-fit directly onto the small black exit spigot.
