Seed sprouter made with Ikea Korken jar. Reusable and washable - for that, I'd suggest using PETG - I made my first one with PLA and I still use it to this day - it got a bit deformed in the dishwasher, but who cares - it still works.
Crazy invention made, so I can appreciate sandwiches with fresh reddish sprouts whenever I want (+/- few days until a new batch is ready)
Apparently, Korken jars are not the same all around the world. This design should fit a jar where external “neck” diameter = 97mm
Slot for that locking wire in the glass lid = 86mm
Mine Korken jar (bought in Poland) was made in Germany
