CO2 bottle under shelf mount

This is an simple under shelf storage mount for CO2 bottles.

This design uses 8mm rods for stability. I used 8mm aluminum rods (hollow) that I cut to a length of 27cm.

Scale the model if you use material that is known to shrink (I used ABS and printed at ≥ 101%). If your printer prints fairly accurate you should be fine or just need a few turns with a drill bit. Rod mounts are designed with 8.1mm diameter which worked fine for me.

I would recommend against PLA.
