Update 220109: On request, added a five-bulb variant with provision for a 6.5mm allen key (CO2 x5 w-6.5.stl). This is based on the low-poly version I've been experimenting with.

A relatively straight forward cradle to hold three, four, five, or six 12g CO2 bulbs, as used for gas powered Airsoft or Gel Blasters, in addition to a 6mm allen key. Keeps your bulbs together and relatively secure when transporting or on the field.

Pictured is the 5-bulb variant.

NB STL file sizes are a bit large due to excessive geometry in the curves. I may revisit these later to reduce the complexity as it is almost entirely superfluous, depending upon popularity and feedback.
