This is a remake of the Sodastream CO2 cylinder holder for 2 cylinders by @Mario modified to clip on IKEA IVAR shelving unit. I also made the walls thicker and added closed “back” with two hex pattern versions - with “small" and “large” holes.
Additional hardware: M4x16 mm bolt and M4 nut
The hole for the M4 nut is with very tight tolerance in order to hold it in place when the holder is installed (instead of using glue), so you need to press the nut firmly into the hole and make sure that it is aligned with the hole by screwing the bolt into it.

Notes:
Print the objects as they are oriented in the .stl files.
[Update 20240307] As suggested by @Rey_241055, the small clip is now available in a separate file. One small clip is required for each of the holders.
Step files added as well.
The author remixed this model.
