Your old aerosol cans don't have to go to waste. This 3D-printed adapter lets you refill dried-out cans with fresh air pressure, so you can use every last bit of product inside.

The adapter works with standard air guns for dust cleaning and handles two common nozzle sizes. A built-in thumb rest gives you the grip you need when pressure builds up. Print it with the circular base down, no supports required.

Safety matters: keep air pressure under 3 bar, wear eye protection, and understand the risks before you start. This design works best with cans that still have liquid but lost their pressure.
