Keycard outside holder for SECRID leather wallets

Since the SECRID wallets are made of metal and thus blocks RFID/NFC, the keycard I use to start the car can't live inside it. So I made this to hold the keycard on the outside of the leather, enabling much easier use. The holder is chamfered on the long edges and fillets added everywhere else, so it won't snag when pulling it out of your pocket. It's held around the leather edges snugly. Some SECRID wallets have slightly thinner leather though, so if you need a tighter fit for some reason, let me know and I'll make it.

There's a solid version and a skeletonized version. I would personally recommend the solid version as the skeletonized version is more likely to snag on things, and doesn't protect the card from scratches (if that matters to you). It's also a little trickier to print and requires fine tuning so that overhangs won't fail.

Note: The pictures shows a version with fillets on the inside flaps. I changed this in the final design to be large chamfers instead in order to improve printability. It doesn't change the outward appearance nor function.

Also note: This will not work with credit cards that have raised characters. The holder is precisely tuned for the thickness of cards without raised characters for a very precise fit.
