I really liked the original design, however I don't know anyone who can afford 11 credit cards. I slimmed it down to hold 5 cards. Just enough to hold your driver's license, one credit card, your Blockbuster card, Subway rewards card, and an Olive Garden gift card from your aunt Irene. Uses 3x3mm magnets.

UPDATE 2024-06-21: Added optional cap and body to accept 3x6mm magnets.

I used tree supports, touching the buildplate only, and printed them using the orientation in the files.
