Spring Loaded Fermentation Lid

Spring loaded mason jar lid burps itself when the pressure in the jar overcomes the springs pressure. Inspired by /u/MechEngBuck. My take on this lid uses a spring from bambu labs, which is much cheaper and easier to source. I also made lids for both wide and regular mouth jars. I included two print profiles. One of them uses a very slight fuzzy skin settings that closely resembles the look of the textured PEI plate. I&#39;d recommend using a smooth plate with the regular print profile and a textured plate with the fuzzy skin profile for a more cohesive look. My preference is to use PETG with a textured plate and the fuzzy skin profile. The spring is a 1x18x15mm compression spring. I used the ones sold on Bambu Labs maker supplies page. Boost Me<3
