Blow-spray airbrush

Blow-Spray Airbrush – Creative 3D Game for Children and Decorators

🖍 Project Description

This blow-spray airbrush is completely 3D printed and designed to be assembled on a plastic coffee cup. It works thanks to the Venturi principle, which allows you to nebulize the paint simply by blowing into the tube.

It is an excellent creative game for children, perfect for experimenting with spray painting in a safe, fun, and educational way. Also ideal for more technical uses such as ceramic coloring, thanks to the ability to spray even denser paints, by appropriately modulating the dilution.

🧩 Technical Features

• ✅ Fully 3D printable
• ✅ Simple assembly with cyanoacrylate glue
• ✅ Compatible with standard coffee cups
• ✅ Blow operation, no batteries
• ✅ Uses the Venturi effect to nebulize the paint

🎨 User Experience

I printed numerous airbrushes for my daughter's scout activity: the children had a lot of fun painting with the spray, creating original effects with stencils and liquid colors.

In addition to recreational use, it has also been successfully tested in ceramic decoration, proving to be practical and effective with denser paints, appropriately diluted.
