ID card holder/ lanyard badge holder

thingiverse

A holder for any standard sized card (ID cards, customer cards, credit cards etc.) which can be attached to a lanyard. Slide in the card from the left side on the back of the holder, then secure it in place by slightly pulling and twisting the lanyard border at the where you slid in the card. the lip of the curverd border piece should be over the card now. The STL called "card holder2" has a slightly different design the only changes are cosmetic.
