I've seen these made out of tuna cans. Put just enough oil to touch the tapered tip on the dipper. Thus oil will not spill out if knocked over. The lid is left loose for cleaning purposes as well as letting oil back into the can as you wipe the dipper off. If you want a more permanent lid, a couple drops of super glue or hot glue will hold it in place. Do no seal the entire lid Oil needs to drip back into the can around the sides of the lid. Gluing the lid to the dipper is another way of securing it. Another way is to print out of ABS, then put a little bit of acetone in the can, Attach the lid and plug the hole with your thumb. Shake the acetone around a bit and poor out the remainder. Let dry for at least 15 minutes. This will seal the lid to the can. Wear gloves and safety glasses!
