ID Card Holder x 3 cards
thingiverse
I hate wearing ID card holders - especially when they start clanking while I walk. This card holder solves that for me. A problem that I encountered was that the retractable cord attached to the card holder wasn't strong enough to retract and hold the card holder with all the cards. I thought about buying one of those Aliexpress retractable cords but they are big like having a wheel rim on your chest. So I just made the card holder lighter. Update: ok so I have modified the button on the card holder. From what I have tested so far I may need to increase the resistance of the middle card. Testing the latest but not sure - may make the card pop out on the side. Please leave comments with your opinion of what I should try - I will prototype and publish them as an .STL
