I wanted a good way to organize my running kit.  

Holds:

1. Tube of Body Glide
2. Running Dynamics Pod
3. Heart Rate Strap
4. Spare watch band
5. Tube of Chap-stick
6. Package of Cliff bar Blocks
7. and 2 hooks that I use for my house key and my Road Id wristband

Additional supplies needed

1. 8 10x2 magnets
2. glue for the magnets only. 

Printing notes

1. Enable rafts when printing the hooks
2. I used 5 walls on the hooks for extra strength
3. Enable support when printing the shell or the magnet holes may not print properly
4. I printed this with PLA Matte, but this should work with any filament
