Credit Card Key Fob

thingiverse

Do you leave your credit card or fuel card exposed in the sun visor? That's a bad idea. Create a key ring holder for your card to ensure you have it with you while driving, without leaving it in the vehicle. Card Fob A offers superior protection for your card and is my top choice. Card Fob B features a finger hole, making it easier to remove the card. Note that cards come in different sizes, so you may need to adjust this design slightly if your card is too tight or loose of a fit. Ideally, the card should slide in and out easily by hand but not be so loose that it falls out when carrying it.
