Credit сard wallet

Credit cards wallet for 3 cards & 1 deeper section to keep several cards or some other stuff like cash or coins.
Holes in card holders are usefull to take out cards, but sometime pieces could be jammed. So, I would like to remove them in next version.
From my opinion best printed with PLA. Outer parts should be glued with superglue or PLA juice created from PLA melted in acetone.
I've added Google SketchUp model, so feel free to customize my work.
