This is a honey gate, designed to fit into the lid or wall of a plastic bucket to allow easy access to honey inside. It is designed to be easy to clean and waste a minimum of honey. You'll need two food-safe 34.5 x 2 mm o-rings for the STL version. You can modify the o-ring variables to suit the o-rings you have, but I wouldn't go smaller than 34.5mm. You'll need two stainless steel M6 bolts and wingnuts to secure the lid to the main bit. I recommend printing on glass so you have two very smooth surfaces touching to form a seal.
