What it does

Fits standard aerosol cans so you control spray paint flow with precision
Push a hot needle through the nozzle to enable spraying, giving you exact paint placement
Enlarged spray chamber directs airflow better, so your paint goes where you aim it
Print on demand in the USA, so you get a custom cap made just for your project

You spray paint with confidence when you have a cap that actually works. This 3D-printed spray can cap gives you the control you need for detailed workshop projects. The enlarged chamber and directed nozzle design let you aim paint exactly where it needs to go.

The cap fits standard aerosol spray cans. To use it, push a hot needle through the nozzle to trigger the spray. This method gives you fine control over paint flow. Your brush strokes become cleaner. Your stencil work comes out sharper. Small details stay crisp instead of getting lost in overspray.

Made in the USA through 3D printing technology, this workshop tool arrives ready to use. No assembly needed. Just attach it to your can and start painting.
