Screw on 5 gallon American Maid water jug bottle cap

thingiverse

Exact 1:1 recreation of screw on cap for American Maid brand 5 gallon water bottle jugs sold at Wal-Mart is needed, as they tend to get lost quickly. Printing out a few extras could be helpful. The original bottle caps feature a thin foam insert in the underside that acts like a gasket or seal. To replicate this in printed caps, you can use a foam plate and cut out a circle that fits inside the cap. This will work just as well as the original caps. If this part is useful to you, feel free to show appreciation by clicking the Tip Designer button on the left. Any tips are greatly appreciated. EDIT: Due to printing tolerances of some printers, if the cap is too tight for your water jugs, simply enlarge/scale it in X and Y directions by 1% for a better fit. To do this, select the part in Cura, hit S on your keyboard for scaling options, disable Uniform Scaling, set X and Y to 101%, and avoid scaling the Z axis or threads will have incorrect pitch.
