This is a storage container for Kyosho Mini-Z tires and wheels.  It will hold a full set and has a snap on lid.   It could be used for other items but it was specifically designed for these tiny tires and wheels.  For reference, the circular cavities inside are about 1.1" in diameter (just under 28mm).

I designed it to be printed with most any rigid material, but I'm printing it with PLA.  The snap on lid can be removed by lightly squeezing the sides of the container (just pulling it off by pure force may break the tabs).

Print as the models are oriented with no supports.
