I bought an EAI Keirin Tote bag, hoping it would help me to organize my track cogs (sprockets), chainrings, and other tools. What I found was that they would keep falling out of the bag, and, it was difficult to know immediately what the tooth count was on a cog (I resorted to writing the count on the cog with a Sharpie). Then, one day, it occurred to me that I could 3D print a threaded track cog organizer! Each cog could be screwed into its designated spot, which would state the tooth count.
This design is for ISO 1.375" x 24 tpi, but it would be easy to adapt to other threading (however, I'd need help to test it). For now I am publishing a six-cog organizer, from 12T to 17T. I designed this with 1.5mm base plate (I tried 1mm but I preferred it to be stiffer), rounded edges, and 4mm separation between cogs. I also have an 18T, so I might in future publish a single or double carrier for the larger cogs.
I printed mine on PLA because track bikes don't generally get wet. Enjoy!
