Alpha Magnetic Bottle Security Cap Opener

I picked up my curbside grocery order during the COVID-19 pandemic in AZ, where we are having one of the worst outbreaks in the world on a per-capita basis. In a state of 7.3 million, there are over 70k confirmed cases. Just based on those numbers, there is more than a 50% chance that a person with COVID-19 is at an event with 90 or more people.

The grocery store forgot to take off the security caps from some of the beverage bottles that I ordered.

Instead of go back to the store and potentially expose myself to COVID-19, I took magnets from an old hard drive, 4 m3 screws, and 2 m4 screws, and made this security cap opener.

Print the object. Screw two hard disk drive magnets on the brackets that they come with in the hard disk onto the object from one direction with m3 screws. Screw m4 screws into the larger holes so that they protrude about 5mm past the face of the magnet.

The magnets will pull the magnetic security pins up against springs that push them down. The m4 screws allow you to turn to release the cap.
