Hi all,
I have designed a small clamp to clip onto the pressure relief valve of the F1 Kegs, keeping them open for fermentation projects that require constant air exposure, such as Kombucha. The clips can be easily 3D printed and fit snugly on the valve, keeping it all the way open.
If you are interested in printing your own or even remixing the model and making it better, I published the STL on Printables. You can find the model here: https://www.printables.com/model/1048269-igulu-f1-keg-pressure-relief-valve-opener
Have fun with it, and I hope it's a useful little helper for your fermentation projects 😊
