About this 3D model

Works.Needs a glass or metal piece to actual burn in depending on your material.What you do with this is your responsibility.Didnt use an adhesion, i suggest a hotter build plate, atleast 65*c. Initial layer speed was lowered to 25mm/s. Inside looks to be smooth and water tight. There is a cap for the water port that has a ring handle. It doesnt fit snugly, but is tight enough it keeps vacuum. Cap may need to be printed seperately with a skirt .
