Fermentation Jar Lid

As a solution to a problem home fermenters face, I made this self-burping mason jar lid. It fits standard mouth mason jars. A spring will be required, and I uses one with a spring constant of approximately 2.5kN/m, with a diameter of 38.5mm. I printed this version with PLA+ and it is able to hold up to the fermentation process and stresses applied. If you have any recommendations, or if you're having issues, please let me know so I can make some upgrades to the part to help out future fermentors!
