I needed a case for my ear plugs that wasn't uncomfortable to have in your pocket, many designs I found online had protruding pieces and bulges that would possibly cause discomfort. So In comes this odd oval shape I came up with.

You'll need four 6mm x 2mm magnets

I set my support overhang threshold to 20 degrees, and used pursa slicers paint on supports tool to prevent supports generating in the magnet holes, or the paracord hole. I used PETG, but most plastics should probably work fine.
