milk juice jug cap water trap

thingiverse

This tiny water trap may be screwed onto the top of an apple cider jug so that you can brew hard cider. There is also a version that fits on the top of a milk bottle. It would probably be good to print it using food safe materials. Assembly of the "straw" piece into the teardrop shaped hole in the cap is necessary. Many printers print slightly too much material, so there is a slight gap (0.2mm) in the model between the hole and the straw to account for this. The straw should press fit into the hole, but gluing may be necessary. I did not use glue after printing with my Creality CR10s, and it works fine for me. It's best to print both pieces upside down so that support material is only required outside of and underneath the straw, and not inside the straw. A raft type build plate adhesion may be required for the straw piece, and no support material or raft should be required for the cap.
