Flexible wallet / card holder

Minimalist cardholder that prints completely flat in one piece using TPU. Features integrated living hinges and a separate tension insert for a secure lock. Simple to print, zero supports needed. By default holds 1 card, but 2 can be also be used (will be tighter fit)

Materials:
- wallet: TPU (I used 95A but any other is fine)
- clip: any non flexible (PLA, PETG, ABS etc)
