Bicycle flat repair kit

I made the mounting holes big enough to fit "profile design" velcro straps to secure this flat kit to the bicycle saddle post. Holds one tube, one CO2 cartridge, and small items such as allen keys and Schrader adapter, money, etc.

v2: I added a back wall so stuff doesn't fall out while you're wrapping the tube around, and I added I slide on lid. I also moved the hole for the stem to the opposite wall and moved it off-center.
