Room for 5 cards
Room for coins, paper money, SD cards, keys, whatever you need (4mm high)
Self-locking mechanism
Slim design (less then 14mm thick!)
Looks cool :)
Easy to print without any supports
How to make
Print everything flat on the bed :)
Insert the lever into the base
Put filament in the holes of the change compartment to align with base
Put glue on change compartment
Set it on the base and let it dry
Put in the lid (I didn't even need to glue anything, it just stays put!)
If you really want smooth filament "nails"...cut off 2cm of filament, heat a piece of metal and press against the filament end and make it curl back to form a nail "head". Cut the piece to length and insert (check my video for the result)
Guys, seriously...have fun and post your make :)
