Got any keyboard cleaning compressed air cans laying around and have no idea what to do with them?? Well now you can turn that boring can into an intimidating weapon of mass amusement! This is a simple, easy, and quick print that will fit any can that has a tube with a .09" diameter, which I think most cans have that here in the US. I guess you could also use any other type of can that has that same tube like WD-40, but that would make a big pointless mess of lubricant on the floor. To shoot, simply slide it on the tube of a compressed air can and press the bottle's nozzle all the way in a quick burst of air. Be careful shooting as it could potentially hurt someone's eye. Make sure to rotate the file so that you print the rocket standing up
