A simple and elegant wallet that has space for 4 cards, one of which can be an embossed card like a credit card (has to be the bottom one due to emboss). 

Model needs 2 magnets (ø10mm x 2 mm) to keep the latch closed and a m3 screw with a 2 mm thick head and 8 mm thread.

For multicolored stripe, change filament which makes a stronger bond, top will have to be glued on, however.
