NOTE - Recommend you use the ‘Halloween’ remix version, specifically version 5 if you're struggling with the toothpicks being too weak or not staying in the cards. Created a v5 print profile over there with stronger attachments.
These little toothpicks will be with you whenever you need them. Simply tuck the credit card carrier into your wallet and snap out a toothpick when you need one. They work really well with modern wallets like: https://www.printables.com/model/261476-assemble-after-print-cascade-card-wallet-remix
Stiffness at default thickness (1mm) is perfect with my PLA filament. Should you find that the flex is too much, you can scale the model vertically to increase the rigidity. With that said, the card thickness needs to be taken into account when using ‘modern’ wallets as it becomes quite important for friction and clearance.
As a bonus, if you look at these long enough, you might get to see the wide open mouth and eyes ;-)
Please note as 3D prints trap bacteria, I would recommend these for one time use only and at your own risk.
Note that the actual toothpick was inspired by a OnePlus SIM ejection tool from the OnePlus 5 (which also makes a great toothpick ;-))
