**Parts Needed** [12 mm x 3 mm neodymium disc magnets](https://www.homedepot.com/p/MASTER-MAGNETICS-1-2-in-Neodymium-Rare-Earth-Magnet-Discs-6-per-Pack-07046HD/202526367) [ISO standard badge loop](https://www.amazon.com/Plastic-ID-Holder-Eyelet-Lanyards/dp/B01GOUWHEG/ref=sr_1_1?keywords=pvc+badge+loop&qid=1570497071&sr=8-1) (sorry, couldn't find a single) **Synopsis** I needed a 6-card badge holder, and I had magnets and a badge holder loop. So this happened. Uses the badge holder loop as a hinge for the two parts, and snaps shut using the magnet on either side. **Magnets and Credit Cards** I did some basic research and found that credit cards should be safe if the magnets are greater than 1.5 mm away from the magnetic stripes. This design should accurately account for that distance. I will be testing the design with my own cards, and I will update on any issues I run into. For the record, usage started on 10/7/2019. **Make Your Own Modifications** [Fusion 360 File:](https://a360.co/30V1cZ1) You can use this file to customize your design. Unfortunately, due to the magnets, the overall design can't get any slimmer. You can, however, easily adjust the inner dimensions to fit more (8 or 9) or fewer (recommend > 2) cards. If you are more comfortable with designing in F360, you can also make the overall design fatter to fit even more cards.
