CO2 Cartridge Protective Cap
thingiverse
Simple rubber cap to protect the threads and to prevent accidental discharge by puncturing the end of the CO2 cartridge(s). Print in TPU, or other flex filament, for best results. I have not tried printing with PLA or similar. I am including a "- 2 Cartridge" version that should fit two cartridges together by placing them side by side in opposite directions, but I have not printed and test fit this design yet. If you do print it and it works please comment or post a Make so I can update this description.
