CO2 bottle stand

After having added CO2 to my aquarium with a free kit we got with a disposable bottle, i wanted to upgrade. The only available bottle i had was a 500 gram CO2 bottle from Aqua Noa, which had a rounded bottom. It was also supplied with a wall mount. due to the limited space i designed this stand so it's easier to operate instead. This bottle stand is designed for a snug fit with bottles with a diameter of 60.5 mm. feel free to resize accordingly for your own bottle.
