CO2 Cartridge Holders

This is my attempt to organize the many different sizes of CO2 cartridges that I use. I primarily use the Leland brand, and I will add the size and part numbers as well as dimensions for all below, at a later date. I tried to design these with relatively tight tolerances for the cartridges listed, so they may or may not work for you. I will also post the effective printed diameter based on my print settings, for each cylinder, at a later date.
