Just my version of the 'savegrabber' door open hooks to help keep you from having to touch doors and use pinpads. Combine with a retractable key chain and you'll always have it when you need it. Remember to sanitize it regularly PETG recommended for this purpose.

This is Version 2. I found the first iteration to have too small of a hook to open some doors, and I found it was weak. I broke several. I also added a pocket clip that you attach with a m4 pan head 10mm screw.

Print at 50% infill at least.
