Tough Credit Card Holder with Tight Drawer for Things

I liked the design I'm remixing. I decided to add a small compartment for a few bills, coins or flash memory cards. The drawer is very tight and there is no way to accidentally open it. The credit card compartment can hold 3 or 4 cards depending on the type of card. There is also an option to place only 1 card on top and place the additional cover.

You need allen bolts:

M3x12- 8 units

M3x5- 8 units
