I made a remixt of @aljaztitoric 's slim card wallet. Now you can add add a chash clipp, an outside card for NFC payment or a keycard and some usb slots.
The wallet is now held together by screws, so if the fit of the cards gets loose you can reprint the side parts and continue using the rest of the parts.
You will need M3x5 and M3x8 screws. The amount of each screw depends on the configuration chosen.
You may need to file some plastic away at the usb slots to get the desired fit.
Print the side parts and the clipp in PETG for sufficient flexibility.
Print top and bottom parts in PLA
