Air pump to Aerosol air refill adapter

My half can of WD 40 ran out of air. Instead of throwing away all that product, I refilled the can with 90 PSI of air.

I have included the Fusion 360 file so you can adjust the size of the aerosol can's nozzle to your liking. I have it set to 3.4mm and did manage to barely fit it to my bottle. It may be shrinkage or my printer.
