This wallet bears an Orcish shield motif on both faces to PROTECT YOUR MONEY or something...

The wallet can be printed in either hard plastics like PLA or in soft/flexible plastics like TPU. Even though it's designed for soft plastics like TPU, In the pictures I included, the white plastic design is actually hard PLA.

There are TWO designs:

Orcish_slim_wallet.stl - includes slots for 4 cards and a center space for "cash".
new_orc_wallet.stl - Includes slots for 6 cards, is 6% wider, and a center space for "cash".

Yes (20%)

You must print this with some degree of infill.

When printing in a hard plastic, I strongly recommend "fattening" it (increase its Y scale by AT LEAST 3-4%) to help be able to better insert and remove cards. I do NOT recommend trying to carry cash in the hard plastic design; the center space just isn't flexible enough for a wad of folded bills.

Flexible plastics shouldn't need to make any adjustments.
