Rotating knitting needle organizer

I designed this to organize my double pointed knitting needles by size, but it can also be used to store crochet hooks or office supplies. It has twelve outer compartments and a slightly higher and bigger one in the middle. It can be printed without the base if you don't need it to rotate. the outer compartments will fit a complete set of 5 dpns each (or more than one for smaller sizes) up to 6mm. There is a version with knitting needle size debossed on each outer compartment, but I made it with the size of needles I have, you might want to personalize it with different sizes. I also added the .f3d file if you want to modify it to fit your need.
