co2 distributor

Hi,
I made this distributor because I wanted a great storage for my
12g Co2 cartridges. Like many of you I play airsoft and so i have
a lot of co2 and now I can stick this to the wall a pick just 1 at the
time and it is very usefull. I gonna make a BB distributor too to reload
the BB loader. Folow me if you want it!

Print as you want, I think 0.4mm with 20% fill seems good.
