Spray Can Air Filling Adapter - Spray Can Saver!

DISCLAIMER: Use at your own risk. We assume no liability for the use of this tool. By downloading this file, you are agreeing to these terms.

This handy little adapter will save you money by refilling your brake cleaner, WD-40 (or any can that has run out of air) - with more air. Simply print this file out, attach it to the end of your spray nozzle, remove the can cap and inject air back into the can so you can use the rest of the liquid that is inside. You can also strip the rubber off a old tire valve and use a tire chuck.

Highly suggest printing it at .1mm layer height on a FDM printer, or .05mm on a SLA printer. Wear safety goggles while doing this as well.

NOTE: This will only work on spray cans that have female nozzle stems. The old school cans with the male nozzles (that plugs into the can), obviously - this will not work on those.

IOWORLF states - upending the can before filling with air can reduce or eliminate the contents spraying back. ALWAYS use eye protection!!!!

DO NOT FILL CANS WITH UNREGULATED AIR. Spray cans are rated to 140psi, please make sure you turn your air regulator down to approx 100 psi for safe margin.
